[TLP:CLEAR] Ivanti Connect Secure fixes an actively exploited vulnerability
Ivanti fixes an actively exploited vulnerability in Ivanti Connect Secure in versions 25.1.1.2, 25.1.3.0, 25.1.3.1 and 22.8R2.5 [1].
Allows an unauthenticated remote attacker, due to a mismatch between the URL used for authorization and the actual target of the request combined with a race condition between the execution and deletion of an uploaded script, to execute arbitrary code with "cgi-server" privileges [1][2]. This vulnerability can be chained with another vulnerability to escalate privileges from "cgi-server" to root, and no fix exists for that vulnerability yet [2]. Both Ivanti and CISA warn of active exploitation of the vulnerability [1][3]. Details can be found at [2].
