CVE-2025-48014
📋 TL;DR
This vulnerability allows attackers to bypass password guessing limits when LDAP authentication is used, enabling brute-force attacks against user accounts. It affects systems using SEL software with LDAP authentication configured. Organizations using affected SEL products with LDAP authentication are vulnerable.
💻 Affected Systems
- SEL software products with LDAP authentication capability
⚠️ 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
Complete account takeover through successful brute-force attacks leading to unauthorized access, data theft, and potential lateral movement within the network.
Likely Case
Successful brute-force attacks against weak passwords, resulting in unauthorized access to user accounts and potential privilege escalation.
If Mitigated
Limited impact if strong password policies, account lockouts, and network segmentation are properly implemented.
🎯 Exploit Status
Exploitation requires network access to the authentication endpoint and knowledge of valid usernames; no special tools needed beyond standard brute-force utilities.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check latest software versions at https://selinc.com/products/software/latest-software-versions/
Vendor Advisory: https://selinc.com/products/software/latest-software-versions/
Restart Required: Yes
Instructions:
1. Visit the SEL software versions page. 2. Identify and download the latest patched version for your product. 3. Follow vendor installation instructions to apply the update. 4. Restart the affected service or system as required.
🔧 Temporary Workarounds
Disable LDAP Authentication
allTemporarily disable LDAP authentication and use alternative authentication methods if available.
Specific commands depend on SEL product configuration; consult product documentation for disabling LDAP auth.
Implement Network Controls
allRestrict access to authentication endpoints using firewalls or network segmentation.
Configure firewall rules to limit LDAP authentication traffic to trusted IP addresses only.
🧯 If You Can't Patch
- Enforce strong password policies (e.g., minimum length, complexity requirements) to reduce brute-force success rates.
- Implement account lockout policies after a limited number of failed login attempts to mitigate unlimited guessing.
🔍 How to Verify
Check if Vulnerable:
Check if LDAP authentication is enabled in your SEL software configuration and verify the software version against the vendor's affected versions list.Check Version:
Command varies by SEL product; typically found in product documentation or administrative interfaces.Verify Fix Applied:
After patching, confirm the software version is updated to a non-vulnerable version and test that password guessing limits are enforced during LDAP authentication attempts.📡 Detection & Monitoring
Log Indicators:
- Multiple failed LDAP authentication attempts from single IP addresses
- Unusual patterns of login failures exceeding normal limits
Network Indicators:
- High volume of LDAP authentication requests to affected systems
- Traffic from unexpected sources to authentication ports
SIEM Query:
Example: 'source_ip=* AND event_type=authentication_failure AND auth_method=LDAP AND count > 10 within 5 minutes'
