Multiple Vulnerabilities in PHPCould Allow for Remote Code Execution

Multiple vulnerabilities have been discovered in PHP, which could allow for remote code execution. PHP is a programming language originally designed for use in web-based applications with HTML content. Successful exploitation could allow for remote code execution in the context of the affected service account. Depending on the privileges associated with the service account, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Service accounts that are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Threat Intelligence Open-source reports have stated that proof of concept exploits are available for CVE-2024-4577.
Systems Affected
PHP versions: 5 – 8.3.7
Risk
Government:
– Large and medium government entities: High – Small government entities: Medium
Businesses: – Large and medium business entities: High
– Small business entities: Medium
Home Users: Low
Recommendations
Apply appropriate patches provided by PHP to vulnerable systems immediately after appropriate testing. Restrict use of certain websites, block downloads/attachments, block JavaScript, restrict browser extensions, etc. Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. Block execution of code on a system through application control, and/or script blocking. Remove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.
