Package : mediawiki Version : 1:1.31.16-1+deb10u7 CVE ID : CVE-2023-3550 CVE-2023-45362 CVE-2023-45363

Multiple vulnerabilities were found in mediawiki, a website engine for collaborative work, that could lead to information disclosure, privilege escalation, or denial of service.

CVE-2023-3550

Carlos Bello reported a stored cross-site scripting (XSS) vulnerability when uploading crafted XML file to Special:Upload, which can lead to privilege escalation. (However .xml file uploads are not allowed in the default configuration.)

CVE-2023-45362

Tobias Frei discovered that diff-multi-sameuser (X intermediate revisions by the same user not shown) ignores username suppression, which can lead to information leak.

CVE-2023-45363

It was discovered that querying pages redirected to other variants with `redirects` and `converttitles` parameters set would cause a denial of service (unbounded loop and RequestTimeoutException).

For Debian 10 buster, these problems have been fixed in version 1:1.31.16-1+deb10u7.

We recommend that you upgrade your mediawiki packages.
