CVE-2022-24083
📋 TL;DR
CVE-2022-24083 is a critical authentication bypass vulnerability in Pega Platform that allows attackers to circumvent local password checks, potentially gaining unauthorized access to affected systems. It affects Pega Platform users with local accounts, particularly in environments where authentication relies on these mechanisms.
💻 Affected Systems
- Pega Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could gain full administrative access to the Pega Platform, leading to data theft, system compromise, or ransomware deployment.
Likely Case
Unauthorized access to sensitive data or functionality within the platform, such as viewing or modifying business processes and user information.
If Mitigated
With proper network segmentation and access controls, impact may be limited to isolated systems, but authentication bypass still poses a significant risk.
🎯 Exploit Status
Exploitation likely requires some access or knowledge of the system, but the bypass mechanism is straightforward once identified.

Check if Vulnerable:
Check the Pega Platform version against the advisory; if running an affected version without the patch, it is vulnerable.Check Version:
Use Pega Platform's administrative interface or command-line tools to check the current version; e.g., run a query in Pega or check system properties.Verify Fix Applied:
Verify that the applied hotfix version matches the one listed in the Pega advisory and test authentication functionality.📡 Detection & Monitoring
Log Indicators:
- Failed or successful authentication attempts from unexpected IPs or users, especially for local accounts.
Network Indicators:
- Unusual traffic patterns to authentication endpoints or unauthorized access attempts.
SIEM Query:
Example: 'source="pega_logs" AND (event_type="authentication" AND result="success" AND user="local_account")'
