Discussion

Ruby Multiple Libraries SSL Multiple Insecure Certificate Validation Weaknesses

Ruby is prone to multiple weaknesses related to its validation of certificates. The problem is that multiple libraries fail to properly perform validity checks on X.509 certificates.

Successfully exploiting these issues may allow attackers to perform man-in-the-middle attacks against applications that insecurely use an affected library. Other attacks may also be possible.

NOTE: These issues are related to a weakness covered by BID 25847 (Ruby Net::HTTP SSL Insecure Certificate Validation Weakness).

Exploit / POC
