Critical CryptoAPI Spoofing Flaw in Windows PoC Exploit Released

 

Proof-of-concept (Poc) code has been made available for a high-severity security vulnerability in the Windows CryptoAPI that Microsoft was notified of by the U.S. National Security Agency (NSA) and the U.K. National Cyber Security Centre (NCSC) last year. 

The CVE-2022-34689 spoofing vulnerability, with a CVSS score of 7.5, was fixed by the tech giant as part of Patch Tuesday updates delivered in August 2022, although it wasn’t made public until October 11, 2022. 

In a then-released advisory, Microsoft warned that “an attacker might alter an existing public x.509 certificate to impersonate their identity and conduct actions such as authentication or code signing as the targeted certificate.” 

The Windows CryptoAPI provides an interface for programmers to integrate cryptographic services, including as data encryption and decryption and digital certificate authentication, into their programmes.
