Summary

CVE-2025-54347 is a critical-severity Path Traversal (CWE-22) vulnerability in Desktopalert Pingalert Application Server. Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 46.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-54347 is a Directory Traversal vulnerability (CWE-22) in the Application Server component of Desktop Alert PingAlert software, affecting versions 6.1.0.11 through 6.1.1.2. The flaw allows an attacker to write arbitrary files under certain conditions, earning a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low attack complexity, and high impacts across confidentiality, integrity, and availability.

An attacker with low privileges (PR:L), such as an authenticated user, can exploit this vulnerability remotely over the network without user interaction. Successful exploitation enables writing arbitrary files, potentially leading to remote code execution, data tampering, or system compromise given the changed scope (S:C) and high impact ratings.

Mitigation details are available in the vendor advisory at https://desktopalert.net/cve-2025-54347/. Security practitioners should review it for patching instructions and workarounds specific to affected PingAlert deployments.
