TITLE

Apple OS X Server of Web Vulnerability that breaks cryptographic protection mechanisms in servers

DESCRIPTION

Web Server in Apple OS X Server before 5.1 supports the RC4 algorithm, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors. Apple Mac OS X Server is prone to the following security vulnerabilities: 1. Multiple security-bypass vulnerabilities 2. Multiple information-disclosure vulnerabilities An attacker can leverage these issues to obtain sensitive information, bypass security restrictions and perform unauthorized actions. The software enables file sharing, meeting scheduling, website hosting, network remote access, and more. Web Server is one of the Web servers. The vulnerability is caused by the program supporting the RC4 algorithm. A remote attacker could exploit this vulnerability to compromise the confidentiality protection mechanism.
