Several vulnerabilities have been discovered in dokuwiki, a standards compliant simple to use wiki. The Common Vulnerabilities and Exposures project identifies the following problems: It was discovered that an internal variable is not properly sanitized before being used to list directories. This can be exploited to list contents of arbitrary directories. It was discovered that the ACL Manager plugin doesn"t properly check the administrator permissions. This allow an attacker to introduce arbitrary ACL rules and thus gaining access to a closed Wiki. It was discovered that the ACL Manager plugin doesn"t have protections against cross-site request forgeries . This can be exploited to change the access control rules by tricking a logged in administrator into visiting a malicious web site. The oldstable distribution is not affected by these problems.
