This is an OCR of the content: The key information regarding the vulnerability is: Name: BREACH Type: Compression side-channel attack Target: HTTPS/SSL-protected web applications Risk: Can be used to extract secret information (like session tokens) from encrypted HTTPS traffic Exploit Mechanics: By injecting known strings into the web application and observing the size of the returned compressed content, an attacker can infer the presence of known strings in the encrypted payload. This can potentially disclose sensitive data such as CSRF tokens, cookies, or other session information. Mitigation: Disable HTTP compression on the server, or ensure that no user-supplied input is reflected in HTTP responses. Source of Vulnerability: HTTP compression combined with a lack of proper measures to prevent such attacks. The attack exploits the way that data is compressed in HTTP responses, which can leak information about the contents of the encrypted data. Status: Active threat demonstrated at Black Hat 2013. Advice from Researchers:** Users and administrators should take steps to prevent HTTP compression vulnerabilities and mitigate the risks posed by the attack. The researchers advise against using HTTP compression unless it is absolutely necessary.
