CVE-2025-54338
📋 TL;DR
An incorrect access control vulnerability in Desktop Alert PingAlert Application Server versions 6.1.0.11 to 6.1.1.2 allows attackers to access and disclose user password hashes. This affects organizations using these vulnerable versions of the notification/alerting software. Attackers can potentially obtain credential hashes that could be cracked offline.
💻 Affected Systems
- Desktop Alert PingAlert Application Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers obtain user password hashes, crack them offline, gain unauthorized access to systems, and potentially move laterally through the network using compromised credentials.
Likely Case
Attackers access user password hashes, attempt to crack weaker passwords, and gain unauthorized access to the PingAlert system or other systems where users reuse passwords.
If Mitigated
With proper network segmentation and strong password policies, attackers may obtain hashes but cannot crack them or use them to access critical systems.
🎯 Exploit Status
The vulnerability allows hash disclosure through incorrect access controls, suggesting relatively straightforward exploitation once the attack vector is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.1.1.3 or later
Vendor Advisory: https://desktopalert.net/cve-2025-54338/
