CVE-2003-1487: Input Validation
Multiple "command injection" vulnerabilities in Phorum 3.4 through 3.4.2 allow remote attackers to execute arbitrary commands and modify the Phorum configuration files via the (1) UserAdmin program, (2) Edit user profile, or (3) stats program.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Restrict access to Phorum's UserAdmin, Edit user profile, and stats interfaces to trusted IP addresses only. Implement this via network firewall rules, a web application firewall, or web-server allowlists (deny-all except trusted IP ranges) to prevent remote access to those components.
- Compensating control
Enable monitoring and blocking for exploitation attempts against the UserAdmin, Edit user profile, and stats programs: configure logs/IDS/WAF to alert on and block requests with command-injection patterns targeting these components, review historical logs for such activity, and block or isolate offending IPs.
- Operational
Inspect Phorum configuration files for unauthorized modifications (compare against known-good backups) and restore from backups if tampering is found. After restoration, rotate all credentials and secrets used by Phorum (administrative accounts and the database credentials) to limit impact of possible compromise.
