SolarWinds Vulnerability Being Actively Exploited By Threat Actors

SolarWinds reports that a high-severity flaw in SolarWinds Serv-U file transfer software exists and should be patched ASAP:

Summary

SolarWinds Serv-U was susceptible to a directory transversal vulnerability that would allow access to read sensitive files on the host machine.

Affected Products

SolarWinds Serv-U 15.4.2 HF 1 and previous versions 

Fixed Software Release

SolarWinds Serv-U 15.4.2 HF 2

Here’s why it should be patched ASAP. Threat actors are currently using it to launch attacks:

Threat actors are actively exploiting a SolarWinds Serv-U path-traversal vulnerability, leveraging publicly available proof-of-concept (PoC) exploits.

Although the attacks do not appear particularly sophisticated, the observed activity underscores the risk posed by unpatched endpoints, emphasizing the urgent need for administrators to apply the security updates.

Rogier Fischer, CEO and Co-Founder, Hadrian had this comment:

“Exploiting this vulnerability can lead to significant issues such as unauthorized data access, resulting in potential data breaches and non-compliance with regulations, from GDPR to HIPAA. Financial implications are considerable, involving not only the costs of incident response and mitigation but also regulatory fines and legal actions from affected customers. In an idea world, organizations utilizing this software would have applied the patch already, considering how big the earlier SolarWinds fiasco was.”

This is another one of those times where you need to drop everything and patch away. Seeing as this exploit is out there and being used by threat actors, you really have no other choice.
