Vulnerability details

The AdRotate Banner Manager plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 5.17.7 via the 'banner' attribute of the adrotate shortcode. This is due to insufficient input validation and sanitization of the…

more

banner shortcode attribute before concatenation into a PHP code string wrapped in W3 Total Cache mfunc or Borlabs Cache fragment markers. This makes it possible for authenticated attackers, with Contributor-level access and above, to execute arbitrary PHP code on the server. This vulnerability requires W3 Total Cache or Borlabs Cache support to be enabled in AdRotate settings.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-34 Non-modifiable Executable Programs
addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

SC-44 Detonation Chambers
addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

SI-10 Information Input Validation
addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

SI-16 Memory Protection
addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
