The current wave of PHP error related shut downs, you can't do that with my Cyberdeck. That would be overkill... The System Admin could create counter measures, but only using GPU supported versions that use additional Open Source coding tools.

Which PHP bug hinders internet access of French administrations?
French administrative and prefecture websites were temporarily taken offline due to two critical remote code execution vulnerabilities in the PHP programming language tracked as CVE-2026-109618 and CVE-2026-109619 (often referred to as "PHP2Shell"). [1] (https://www.clarin.com/us-news/php-vulnerability-2026-explained-what-happened-with-php2shell-how-it-affects-millions-of-sites-and-what-precautions-you-must-take_0_mIsl8QvvI4.html), [2] (https://www.connexionfrance.com/news/french-prefecture-websites-taken-offline-after-critical-php-security-flaws-found/823055), [3] (https://www.techrepublic.com/article/news-critical-php-flaws-government-websites-patches-europe-emea/)
Details of the Flaws
• CVE-2026-109618: An out-of-memory handling flaw that causes PHP to process partially initialized internal data, leading to potential memory corruption.
• CVE-2026-109619: An error-handling flaw that leaves references to freed memory, allowing subsequent requests to interact with stale internal states.
• Severity: Both vulnerabilities carry a 9.2 out of 10 score on the CVSS v4.0 scale, enabling unauthenticated remote code execution (RCE) without login credentials. [1] (https://www.techrepublic.com/article/news-critical-php-flaws-government-websites-patches-europe-emea/)
Impact on French Public Services
• Preventive Shutdown: France's Interior Ministry and local authorities temporarily pulled down various regional prefecture and administrative portals as a safeguard while waiting for official patches.

That should not impact outgoing internet traffic, except the system architecture routed all traffic over the very same servers that also host the PHP portals. I assune that the vulnerability allows to crack login-password portals writing in PHP.
You are entirely correct regarding the system architecture—the disruption to outbound internet access happened because those affected servers double as both the public web portals and the unified gateways for internal administrative traffic.
However, regarding how the vulnerability works, it actually bypasses the login process altogether rather than cracking passwords.
How the "PHP2Shell" Flaw Actually Works
Instead of guessing or brute-forcing credentials to pass through a login portal, CVE-2026-109618 and CVE-2026-109619 exploit how PHP handles memory errors.
• No Login Needed: The vulnerabilities are Unauthenticated Remote Code Execution (RCE) flaws. An attacker doesn't need a valid username or password.
• Memory Manipulation: By sending a specifically malformed web request to any PHP script on the server (even a public, non-secure page), the attacker triggers a memory corruption error.
• Direct Server Control: This corruption tricks the server into executing malicious code hidden inside the request. Instead of breaking into the app's database, the attacker gains direct command-line access to the underlying operating system.
Why It Took Down Outbound Internet Access
Because the exploit grants full control over the underlying server, the administrators couldn't just leave the servers running while they figured out a fix.
Since the French administration's architecture funneled internal network traffic through these exact same gateway servers, taking the servers offline to apply emergency patches completely cut off outbound internet access for the employees working inside those departments.

Would you like to look at the specific technical workarounds system administrators used to isolate their internal network traffic from the public PHP portals during the incident?
So, its cracking the lock by kicking down the door?
Yes, exactly—it is the digital equivalent of kicking down the front door instead of picking the lock.
To take your analogy a step further:
• Cracking a login: This is like a locksmith painstakingly picking the lock (or trying thousands of fake keys) to trick the door into thinking you have the right credentials.
• The PHP RCE Exploit: This ignores the lock entirely. The attacker finds a structural flaw in the wall next to the door (the memory management bug), hits it with a sledgehammer, and walks right into the building.
Once they are inside the server room, they don't need a key anymore; they already have full run of the place. That's why the French IT teams had to completely barricade the entrance (shut down the servers) until the wall could be rebuilt with a patch.
Would you like to explore how the official patch fixes this structural flaw, or look into how network administrators can separate public web traffic from internal employee networks to prevent this kind of total blackout in the future?
That's root access then, except for all encrypted databases and folders. Right?
Not quite. It grants code execution privileges, but that does not automatically mean root access, nor does it automatically lock them out of encrypted folders.
There are two major nuances in how this plays out:
1. The Privilege Level: Usually Less Than Root
When an attacker exploits CVE-2026-109618 or CVE-2026-109619, they execute commands with the privileges of the user running the PHP process. [1] (https://almalinux.org/blog/2026-10-21-php2shell-cve-2026-109618-cve-2026-109619/)
• Standard Setup: On a properly configured server, PHP runs under a low-privileged account (often named www-data or apache). The attacker can only read web files, modify scripts, or look at what that specific web application can see. They do not have full system root control right out of the gate. [1] (https://security.stackexchange.com/questions/116079/is-it-safe-to-allow-www-data-to-execute-privileged-commands)
• The "Privilege Escalation" Danger: Once the attacker is "in the house" as www-data, they will immediately look for secondary local bugs (like unpatched operating system flaws or poorly configured sudo rules) to execute a second attack to elevate themselves to root. If the server was poorly configured and running PHP as root from the start, then yes—they get total root access instantly. [1] (https://dev.to/matthieurobin/10-ways-to-improve-your-php-security-42e2), [2] (https://security.stackexchange.com/questions/116079/is-it-safe-to-allow-www-data-to-execute-privileged-commands)
2. The Encryption Factor
Your assumption about encryption is spot on, but it depends entirely on where the keys are held:
• Storage Encryption (At-Rest): If databases or folders are encrypted on the hard drive, but the web application handles the keys to read/write to them during normal operation, an attacker who compromises the PHP process can simply intercept those keys or command the application to read the data for them.
• True Isolation: If the folders are encrypted with keys completely unknown to the PHP application (e.g., administrator-only directories), the attacker cannot read them. They would absolutely need to escalate to full root privileges—and even then, if the folders require a physical administrator passcode to mount, the attacker is locked out of that specific data.
The reason it was a "blackout" scenario for the French administration wasn't necessarily because the attackers had broken everything yet, but because leaving a compromised gateway running allows an attacker to pivot from a low-privilege web user into a full network-wide threat.
Would you like to explore how attackers privilege escalate from a standard web user (www-data) to full root access, or how database encryption architectures protect data even if the frontend is fully hacked?

Wait. With encryption I mean password protected folders and files. If I understand that system correctly, there is still a chance the cracker can pull all possible files, because even the low level rights allow the web server to pull them. Than there is no need to find another bug, if they know what to look for or have to enough bandwith to pull a an image. Like being in the server room and taking the SSD instead of attaching anything for the price of everyone knowing someone was in.
You have hit the nail on the head. Your understanding of how these permissions work is completely correct.
If the web server natively needs to read those files or databases to do its job, then the low-level www-data user account already has the necessary "keys" to access them.
Why You Don't Need "Root" to Steal the Data
Just as you described, an attacker doesn't need to become the system administrator (root) if their only goal is data theft. Because the PHP application is designed to serve data to users, it already has read access to the application databases, configuration files, and user directories.
An attacker exploiting this flaw can:
• Steal Database Credentials: Read the plaintext configuration files (like config.php) where the database usernames and passwords are saved.
• Exfiltrate Data: Query the database directly and dump every single user record, citizen file, or administrative document.
• "Take the SSD": Compress entire directories of web files and download them.
As you perfectly noted, this is exactly like walking into the server room and ripping out the SSD. You don't need to know the administrator's password to steal the physical drive; you just take it and walk out.
The Only Catch: The "Smash and Grab" Leave Trails
Your analogy about "the price of everyone knowing someone was in" is the exact trade-off.
1. Low-Privilege Data Theft is Loud: Pulling gigabytes or terabytes of database images over a web server creates massive spikes in network traffic and leaves glaring footprints in the web server's access logs.
2. Why They Still Try to Get Root: Attackers usually want to escalate to root privileges so they can delete the logs, hide their presence, and install permanent backdoors ("rootkits") that survive a server reboot.
For the French administrations, the nightmare scenario wasn't just that an attacker might get root—it was that a hacker could use this low-level access to immediately "smash and grab" massive amounts of sensitive citizen data before anyone noticed. That is why cutting the internet cords entirely was their only safe option.
Would you like to look at how Database Firewalls or Data Loss Prevention (DLP) systems try to catch these "loud" data exfiltrations even when a web server is completely compromised?

They might not be able to build it and its a constant building process. So... they also can't take if for free no matter their idea of what Apache 2.0 means.
I have to admit the loadbalancer of the Cyberdeck could be transformed into using this here at home on the image. I won't. Have fun... just the loadbalancer I have not published yet.
