Chain of evidence and sources
OpenAM 16.1.4 öncesi sürümlerde sertifika CRL denetimi sırasında sunucu taraflı istek sahteciliği zafiyeti bulunmaktadır.
Saldırganlar bu açığı kullanarak dahili ana bilgisayarlara istek yönletebilir ve CRL verilerini değiştirebilir.
Show the technical text from the sources
OpenAM before 16.1.4 contains a server-side request forgery vulnerability in certificate CRL checking that fetches CRLs from the distribution point named in a presented certificate without restricting the destination or verifying the downloaded CRL's signature. Attackers holding a trusted-CA-chained certificate can make OpenAM request internal hosts, capture configured CRL update credentials, overwrite stored revocation data to block certificate authentication for that CA, and tie up authentication threads.
