[Announce] CVE-2016-4437: Apache Shiro information disclosure vulnerability Jun 03 2016 03:46PM
Brian Demers (bdemers apache org)
Severity: Important

Vendor:
The Apache Software Foundation

Versions Affected:
1.0.0-incubating - 1.2.4

Description:
A default cipher key is used for the "remember me" feature when not
explicitly configured. A request that included a specially crafted
request parameter could be used to execute arbitrary code or access
content that would otherwise be protected by a security constraint.

Mitigation:
Users should upgrade to 1.2.5 [1], ensure a secret cipher key is
configured [2], or disable the "remember me" feature. [3]

All binaries (.jars) are available in Maven Central already.

References:

[3] If using a shiro.ini, "remember me" can be disabled adding the
following config line in the '[main]' section:
securityManager.rememberMeManager = null
