- 漏洞讨论

Subversion is reported to contain access control bypass vulnerabilities in its 'mod_authz_svn' Apache module.

These access control vulnerabilities present themselves when users have mixed access to a repository.

These vulnerabilities exist in several server operations, such as COPY and DELETE. These operations fail to properly implement the operator assigned access controls, allowing users improper access to repositories.

These issues are only present when using the WebDAV access method with the Apache 'mod_authz_svn' module, with the 'AuthzSVNAccessFile' configuration directive.

The vulnerabilities are present in version 1.0.5 and prior. Versions 1.0.6 and 1.1.0-rc1 have been released to address these vulnerabilities.

- 漏洞利用

No exploit is required.
