CISA KEV Advisory
Srimax Output Messenger Directory Traversal Vulnerability
Srimax Output Messenger contains a directory traversal vulnerability that allows an attacker to access sensitive files outside the intended directory, potentially leading to configuration leakage or arbitrary file access.
Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
Risk Analysis
This directory traversal vulnerability in Srimax Output Messenger allows an attacker to access sensitive files outside the intended directory, potentially leading to configuration leakage or arbitrary file access. The high EPSS score of 0.46075 indicates a significant likelihood of exploitation, and its presence in the KEV catalog confirms it has been actively exploited.
Active exploitation of this vulnerability has been observed in the wild, and it is listed in CISA's Known Exploited Vulnerabilities catalog. The nature of the flaw suggests it could be remotely exploitable.
Review and apply any available patches or updates for Srimax Output Messenger. Implement strict input validation and access controls to prevent directory traversal attacks.
Technical Analysis
CVE-2025-27920 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-27920 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
