March 3rd, 2016: Bezeq's firsty hotfix to authorization bypass vulnerability. March 20th, 2016: disclosure, assigned DWF-2016-91000. Technical details ============= This firmware might reside in Netgear's own firmware as well, but was found on Bezeq firmware (custom). Issues: 1. HTTP Authorization bypass: by supplying "ess_" in the URL, authorization is not validated. 2. Command injection: the ping utility allows an attacker to run arbitrary command via the "system" API, by injecting either a pipe or backticks. 3. CSRF exposure. 4. Possible memory corruption: the basic authorization username is copied via unsafe strcpy to a global variable. Blog post and POC code ===================== http://securitygodmode.blogspot.com
