CVE-2025-5962
📋 TL;DR
A local privilege escalation vulnerability in Lightspeed history service allows unprivileged users on the same system to access and manipulate other users' chat history. Attackers can view, delete, or inject malicious history entries to deceive users into executing harmful commands. This affects systems running vulnerable versions of Lightspeed with local user accounts.

⚠️ Risk & Real-World Impact
Worst Case
An attacker could inject malicious commands into another user's history, leading to privilege escalation, data theft, or complete system compromise through social engineering.
Likely Case
Local users accessing and manipulating each other's chat history, potentially leading to confusion, data loss, or execution of unintended commands.
If Mitigated
Limited to isolated systems with strict user separation or where the service is disabled.
🎯 Exploit Status
Exploitation requires local access and knowledge of inter-process communication mechanisms. No public exploit code mentioned in references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisories RHSA-2025:16345 and RHSA-2025:16346 for specific patched versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2025-5962
Restart Required: Yes
Instructions:
1. Update system using package manager (e.g., 'yum update' for RHEL). 2. Apply patches from Red Hat advisories. 3. Restart the Lightspeed history service or reboot system.
🔧 Temporary Workarounds
Disable Lightspeed history service
linuxTemporarily disable the vulnerable service to prevent exploitation.
systemctl stop lightspeed-history
systemctl disable lightspeed-history
Restrict service permissions
linuxConfigure stricter access controls on the service to limit user interactions.
chmod 750 /path/to/lightspeed-history-service
setfacl -m u:serviceuser:rwx /path/to/service
🧯 If You Can't Patch
- Isolate systems to prevent multiple local users from accessing the same instance.
- Implement strict user separation and monitor for unusual inter-process communication activity.
🔍 How to Verify
Check if Vulnerable:
Check if Lightspeed history service is running and review version against Red Hat advisories: 'systemctl status lightspeed-history' and 'rpm -q lightspeed-history'.Check Version:
rpm -q lightspeed-historyVerify Fix Applied:
Verify service version after update: 'rpm -q lightspeed-history' matches patched version from advisories, and test local user access attempts fail.📡 Detection & Monitoring
Log Indicators:
- Unusual inter-process communication attempts to Lightspeed history service
- Failed access attempts from unauthorized users
- Unexpected modifications to chat history files
Network Indicators:
- Not applicable - local exploitation only
