Threat Advisory: Multiple Vulnerabilities in PHP Could Allow for Arbitrary Code Execution
September 17, 2018
The Multi-State Information Sharing & Analysis Center (MS-ISAC) has released an advisory on multiple Hypertext Preprocessor (PHP) vulnerabilities. An attacker could exploit one of these vulnerabilities to take control of an affected system.
PHP lives in almost every environment in today’s cyber landscape. The advisory outlines a broad set of vulnerabilities affecting multiple versions of PHP. While there has not been any evidence of adversaries using these vulnerabilities to date we recommend that all users and administrators:
- Verify last code changes to PHP sites prior to patching
- Verify PHP level of access
- Update all affected servers
PHP Vulnerability Example:
An adversary compromises lumberyard[.]com with expectations that users from treelogging[.]com will visit the site. The adversary can then use lumberyard[.]com site to further compromise additional treelogging[.]com users and assets. In this example we strongly recommend users not click on unsolicited links.
