SolarWinds Fixes Severe Serv-U Vulnerability (CVE-2024-28995): Overview, Impact, and How IONIX Helps
By Nethanel Gelernter, Co-Founder and CTO | June 16, 2024
Introduction
SolarWinds recently addressed a critical security flaw, CVE-2024-28995, in its Serv-U Managed File Transfer and Secure FTP software. This directory traversal vulnerability, discovered by Hussein Daher, allows unauthenticated attackers to access sensitive files on the host system. The flaw is severe due to its remote exploitability and lack of required user interaction.
Understanding CVE-2024-28995
CVE-2024-28995 affects SolarWinds Serv-U versions up to 15.4.2 HF 1. Attackers can exploit this directory traversal flaw to access files and directories outside the web server’s root, potentially exposing system configurations and user credentials. The vulnerability is trivially exploitable and poses a high risk to organizations using affected versions.
Technical Details & Impact
- Exploitability: Remote, unauthenticated, no user interaction required.
- Potential Impact: Exposure of sensitive files, system compromise, further exploits.
- Severity: High (due to ease of exploitation and potential data exposure).
SolarWinds’ Response
SolarWinds released Serv-U 15.4.2 HF 2 hotfix to patch the vulnerability. The update is available for both Windows and Linux (32/64-bit). Organizations are strongly advised to upgrade immediately.
Steps for Mitigation
- Update: Upgrade to Serv-U 15.4.2 HF 2 immediately.
- Patch Installation: Stop Serv-U processes, replace files as per instructions, restart the software.
- Verify Integrity: Check logs and monitor network traffic for signs of compromise.
- Regular Audits: Maintain up-to-date software and conduct regular security reviews.
