Detection & IOCsextracted from sources · hover to see the quote

  • The vulnerability affects Apache Shiro's default 'remember me' cookie configuration, making the cookie susceptible to a padding oracle attack. Detection should focus on anomalous patterns of requests targeting the rememberMe cookie (e.g., high volume of requests with varying cookie values indicative of padding oracle probing).
  • ·The vulnerability is only exploitable when using the default 'remember me' configuration in Apache Shiro versions before 1.4.2. Deployments using a custom/non-default rememberMe configuration may not be affected.
