The Pakistan Telecommunication Authority (PTA) has issued a notice regarding a serious new threat in PHP vulnerability that potentially affects Windows systems as a result of supporting CGL.
The Pakistan Telecommunication Authority (PTA) has hardened its communications in light of a new Vulnerability criminology found in PHP that can be easily exploited on Windows servers. This flaw designated CVE-2024-4577, allows unauthorized remote code execution due to the injection of a CGI argument that could result in bypassing a code that has been previously revised in its impact, CVE-2012-1823. The flaw impacts several versions of PHP deployed on Windows operating systems, making such servers susceptible to attacks whose objective is arbitrary code execution.

In the words of the PTA, the flaw affects PHP versions 8.3 under 8.3.8, 8.2 under 8.2.20, and 8.1 under 8.1.29. The attack vector is capable of succumbing the target’s network through remote code execution thus it poses high risks to networks that run on an outdated system. The advisory declares that the threat is critical and invokes measures which should be taken urgently to pre-empt risks of aggression from malicious online attackers. The PTA has given some directives, how this risk could be covered. Users are requested to update their PHP as per the newest versions available at php.net.The recommendation to move to such secure designs as Mod-PHP, Fast CGI or PHP-FP has also been made to minimize the attack surface. Administrators are also called to perform updates of all systems and software with the latest security fixes on a routine basis to protect the systems from known exploits.

It is worth noticing the concept of alertness and active response mechanisms to incidents. Affected users are encouraged to report any breach or exploit of the PTA to its CERT Portal or through email. This is aimed at ensuring that there is a response to any attacks leveraging this vulnerability, which in all cases has a low overall effect.
Conclusion: The cybersecurity alert that PTA has released in relation to the PHP vulnerabilities calls for urgent attention in regard to all Windows-based servers with PHP installations, and the call encompasses upgrades and security measures. If the proposed recommendations are followed, the harm can be lessened, and the harm from outside sources can be avoided.
