VAR-202001-0112

Vulnerability from variot - Updated: 2024-08-14 13:25

Cisco IronPort Web Security Appliance up to and including 7.5 does not validate the basic constraints of the certificate authority which could lead to MITM attacks. When there is an error in verifying the \"basicConstraints\" parameter of the certificate in the certificate chain, it can be used to forge the certificate of any domain and obtain the encrypted information through the man-in-the-middle attack. Successfully exploiting these issues will allow attackers to bypass security restrictions and perform unauthorized actions. The program offers features such as Web Reputation Filter (WBRS) and anti-malware scanning engine. The vulnerability is caused by the program not properly handling SSL and TLS security certificates. A remote attacker can exploit this vulnerability to implement a man-in-the-middle attack
