Versions of MyBB (MyBulletinBoard) prior to 1.6.17 are affected by the following vulnerabilities :

  • Multiple unspecified flaws exist that allow stored cross-site scripting (XSS) attacks. These flaws exist because the program does not validate input before returning it to users. This may allow an authenticated remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
  • A flaw in ACP login as HTTP requests do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. By tricking a user into following a specially crafted link, a context-dependent attacker can perform a Cross-Site Request Forgery (CSRF / XSRF) attack causing the victim to perform unspecified actions.
  • A flaw exists that is due to the cache handler using 'var_export' without encoding checks. This may allow an attacker to have an unspecified impact.
