Detection Guidance

Detection of this Local File Inclusion (LFI) vulnerability can involve monitoring for exploitation attempts that try to include local files via the Sala WordPress theme. While specific commands are not provided, typical detection methods include reviewing web server logs for suspicious requests attempting to include files, such as requests containing patterns like "include=", "require=", or file path traversal sequences (e.g., "../"). Additionally, using network monitoring tools to detect unusual HTTP requests targeting the Sala theme endpoints may help. Patchstack recommends professional incident response and server-side malware scanning rather than relying solely on plugin-based scanners, which may be tampered with by malware. [1]
