Impact

Sensitive files such as configuration files, credentials, or system files can be read, potentially leading to further compromise. With a CVSS score of 9.1 (CRITICAL), this represents a critical risk.
Exploit ScenarioDerived

An attacker modifies a file parameter to include directory traversal sequences (../../etc/passwd) to read arbitrary files from the server filesystem.

AnalysisAIv1 – Mar 15, 2026

Emlog Pro 2.5.20 has an arbitrary file deletion vulnerability. This vulnerability stems from the admin/template.php component and the admin/plugin.php component. They fail to perform path verification and dangerous code filtering for deletion parameters, allowing attackers to exploit this feature for directory traversal.

Executive ViewAI

Why It Matters

Organizations using Emlog Pro 2.5.20 face critical risk from CVE-2025-61318 rated CVSS 9.1. Successful exploitation could critically impact the confidentiality, integrity, and availability of affected systems. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
