YesWiki versions before 4.6.7 have a cross-site request forgery (CSRF) vulnerability in the autoupdate UpdateAction. This flaw allows attackers to delete installed packages by tricking a logged-in administrator into clicking a crafted link. The vulnerability can be exploited via unprotected GET requests with specific parameters, potentially removing critical extensions like bazar and disrupting core site functionality.
AI Analysis
Technical Summary
The vulnerability in YesWiki prior to version 4.6.7 is a CSRF issue affecting the autoupdate UpdateAction. Attackers can exploit this by sending a specially crafted GET request containing action=delete and a package parameter to delete installed extensions. Because the request is unprotected against CSRF, a logged-in administrator can be coerced into executing this request, leading to removal of extensions such as bazar, which can break essential site features.
Potential Impact
Successful exploitation results in the deletion of installed packages/extensions, including critical ones like bazar. This can lead to loss of functionality and potentially disrupt the operation of the YesWiki site. The CVSS score of 7.1 (high) reflects the significant impact on availability and integrity, although confidentiality is not affected.
Mitigation Recommendations
A fix is available in YesWiki version 4.6.7. Users should upgrade to version 4.6.7 or later to remediate this vulnerability. Until patched, administrators should avoid clicking untrusted links while logged in and consider implementing additional CSRF protections if possible.
