Online network range scanner for Heartbleed vulnerability by Pentest-Tools.com [161] Official Red Hat offline scanner written in the Python language [162] Qualys SSL Labs' SSL Server Test [163] which not only looks for the Heartbleed bug, but can also find other SSL/TLS implementation errors. Browser extensions, such as Chromebleed [164] and ...
The bar mitzvah attack is an attack on the SSL/TLS protocols that exploits the use of the RC4 cipher with weak keys for that cipher. [1] [2] While this affects only the first hundred or so bytes of only the very small fraction of connections that happen to use weak keys, it allows significant compromise of user security, for example by allowing the interception of password information [2 ...
A server implements an HSTS policy by supplying a header over an HTTPS connection (HSTS headers over HTTP are ignored). [1] For example, a server could send a header such that future requests to the domain for the next year (max-age is specified in seconds; 31,536,000 is equal to one non-leap year) use only HTTPS: Strict-Transport-Security: max-age=31536000.
The CCS Injection Vulnerability (CVE-2014-0224) is a security bypass vulnerability that results from a weakness in OpenSSL methods used for keying material. [80] This vulnerability can be exploited through the use of a man-in-the-middle attack, [81] where an attacker may be able to decrypt and modify traffic in transit. A remote unauthenticated ...
In computer network security, session fixation attacks attempt to exploit the vulnerability of a system that allows one person to fixate (find or set) another person's session identifier. Most session fixation attacks are web based, and most rely on session identifiers being accepted from URLs (query string) or POST data.
The vulnerability can be tested with the following command: env x = '() { :;}; echo vulnerable' bash -c "echo this is a test" In systems affected by the vulnerability, the above commands will display the word "vulnerable" as a result of Bash executing the command "echo vulnerable" , which was embedded into the specially crafted environment ...
The weak-key-generation vulnerability was promptly patched after it was reported, but any services still using keys that were generated by the old code remain vulnerable. A number of software packages now contain checks against a weak key blacklist to attempt to prevent use of any of these remaining weak keys, but researchers continue to find ...
