A not too long ago patched high-risk flaw affecting the SolarWinds Serv-U file switch software program is being actively exploited by malicious actors within the wild.
Vulnerability,monitoring CVE-2024-28995 (CVSS rating: 8.6), Fears An unintentional listing error may enable attackers to learn delicate information on the host machine.
It impacts all prior software program releases together with Serv-U 15.4.2 HF 1, and has been addressed by the corporate within the launch Serv-U 15.4.2 HF2 (15.4.2.157) was issued earlier this month.
Record of merchandise weak to CVE-2024-28995 is beneath –
- SurfU FTP Server 15.4
- SurfU Gateway 15.4
- Serv-U MFT Server 15.4 and
- ServU file server 15.4
Safety researcher Hussein Daher of Internet Immunify is credited with discovering and reporting the flaw. After public disclosure, further Technical details And a Proof of concept The PoC exploit has been made obtainable since then.
