SolarWinds has issued an emergency patch after a critical security hole in its Serv-U Managed File Transfer and Serv-U Secure FTP was spotted being exploited in the wild.<\/p>\n

The vulnerability, discovered by Microsoft’s Threat Intelligence Center (MSTIC) and Offensive Security Research teams, can be exploited by an attacker to achieve remote code execution, and is present in Serv-U version 15.2.3 HF1 and all prior builds. The Redmond crew also said a “single threat actor” was abusing the programming blunder (CVE-2021-35211) though it’s not known how many customers are affected.<\/p>\n

“This attack is a Return Oriented Programming (ROP) attack,” said SolarWinds in an advisory<\/a>. “When exploited, the vulnerability causes the Serv-U product to throw an exception and then intercepts the exception handling code to run commands. Please note, several reasons exist for exceptions to be thrown, so an exception itself is not necessarily an indicator of attack.”<\/p>\n
