Apache Shiro vulnerabilities

Apache Shiro before 1.3.2 allows attackers to bypass intended servlet filters and gain access by leveraging use of a non-root servlet context path.

Apache Shiro 1.x before 1.2.3, when using an LDAP server with unauthenticated bind enabled, allows remote attackers to bypass authentication via an empty username or password.

A remote attacker can inject LDAP special characters into the Distinguished Name (DN) construction in DefaultLdapRealm class. User-supplied username input is directly concatenated into the LDAP DN template without any escaping, allowing manipulation of the DN structure used for LDAP bind authentication.

Apache Shiro, before 1.12.0 or 2.0.0-alpha-3, may be susceptible to a path traversal attack that results in an authentication bypass when used together with APIs or other web frameworks that route requests based on non-normalized requests.

When Apache Shiro is used with the Jakarta EE integration module, a low-privileged user can craft an HTTP request that causes the server to initiate a connection to an attacker-controlled URL and transmit attacker-controlled data. This vulnerability affects Apache Shiro versions 2.x through 3.0.0 only in deployments that use the Jakarta EE integration module. Upgrade to version 3.0.1 or later fixes the issue. Alternatively, set the org.apache.shiro.form-resubmit-host and org.apache.shiro.form-resubmit-port system properties to restrict the host and port that Shiro will connect to when resubmitting a form.

The Jakarta EE module in Apache Shiro (versions 2.0-alpha to 2.2.0 and 3.0.0-alpha-1) uses the HTTP Referer header for redirect after login. Insufficient validation of this client-controlled header could allow an attacker to influence the redirect target.

Apache Shiro versions 2.0-alpha to 2.1.0 and 3.0.0-alpha-1, when using the shiro-jakarta-ee module, are vulnerable to Open Redirect and SSRF. After login, the shiroSavedRequest cookie was not validated, allowing redirect to arbitrary URLs and server-side GET requests.

Default configurations of Apache Shiro send sensitive cookies (JSESSIONID and rememberMe) in HTTPS sessions without the 'Secure' attribute. Affects versions 1.0 to 2.1.0 and 3.0.0-alpha-1. Fixed in 2.1.1 and 3.0.0-alpha-2.

Default configurations of Apache Shiro have a session fixation vulnerability. Affects versions 1.0 to 2.1.0 and 3.0.0-alpha-1. In affected versions, when a session already exists, it is not invalidated upon successful login, nor is a new session generated with a new ID. Users are recommended to upgrade to version 2.1.1 or 3.0.0-alpha-2.

Vulnerability in Apache Shiro allows authentication bypass by varying the case of filenames in requests for static files. If static files are served from a case-insensitive filesystem (e.g., default macOS), an attacker can access files not covered by Shiro filters. Affects versions before 2.0.7.
