What is CVE-2023-2158?
CVE-2023-2158 is a critical vulnerability in Synopsys Code Dx, published on 27 Apr 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Code Dx versions prior to 2023.4.2 are vulnerable to user impersonation attack where a malicious actor is able to gain access to another user's account by crafting a custom "Remember Me" token. This is possible due to the use of a hard-coded cipher which was used when generating the token. A malicious actor who creates this token can supply it to a separate Code Dx system, provided they know the username they want to impersonate, and impersonate the user.
