CVE-2025-62181
📋 TL;DR
Pega Platform versions 7.1.0 through Infinity 25.1.0 have a user enumeration vulnerability in the deprecated basic authentication feature. Attackers can determine valid usernames by analyzing response time differences during authentication attempts. This affects systems using basic authentication, which is deprecated starting in version 24.2.
💻 Affected Systems
- Pega Platform
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Attackers build a list of valid usernames for credential stuffing or targeted attacks, potentially leading to account compromise.
Likely Case
Attackers enumerate valid usernames to facilitate brute-force attacks against known accounts.
If Mitigated
Limited to username discovery only; no password exposure or direct access.
🎯 Exploit Status
Exploitation requires timing analysis tools; no public exploit code known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 24.1.4, 24.2.4, 25.1.1
Vendor Advisory: https://support.pega.com/support-doc/pega-security-advisory-j25-vulnerability-remediation-note
Restart Required: Yes
Instructions:
1. Upgrade to patched versions: 24.1.4, 24.2.4, or 25.1.1. 2. Restart Pega services. 3. Verify basic authentication is disabled if not needed.
🔧 Temporary Workarounds
Disable Basic Authentication
allDisable the deprecated basic authentication feature entirely.
Configure authentication settings to use modern mechanisms (OAuth, SAML, etc.)
Implement Rate Limiting
allAdd rate limiting on authentication endpoints to prevent enumeration attempts.
Configure web server or application firewall to limit authentication requests per IP
🧯 If You Can't Patch
- Disable basic authentication and migrate to modern authentication mechanisms.
- Implement network-level controls to restrict access to authentication endpoints.
🔍 How to Verify
Check if Vulnerable:
Check if basic authentication is enabled and version is within affected range.Check Version:
Check Pega Platform version in administrative interface or configuration files.Verify Fix Applied:
Verify version is 24.1.4, 24.2.4, 25.1.1 or later, and basic authentication is disabled.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts with varying usernames
- Unusual timing patterns in authentication logs
Network Indicators:
- High volume of authentication requests from single IPs
- Patterns of username enumeration attempts
SIEM Query:
source="pega" AND event="authentication" | stats count by username, src_ip | where count > threshold
