The impact of this vulnerability is mitigated by the need for an attacker to have commit privileges to a Subversion repository exposed by an otherwise trusted ViewVC instance. The attack vector involves files with unsafe names (names that, when embedded into an HTML stream, would cause the browser to run unwanted code), which themselves can be challenging to create. Users should update to at least version 1.2.2 (if they are using a 1.2.x version of ViewVC) or 1.1.29 (if they are using a 1.1.x version).\n\nViewVC 1.0.x is no longer supported, so users of that release lineage should implement a workaround. Users can edit their ViewVC EZT view templates to manually HTML-escape changed paths during rendering. Locate in your template set's `revision.ezt` file references to those changed paths, and wrap them with `[format \"html\"]` and `[end]`. For most users, that means that references to `[changes.path]` will become `[format \"html\"][changes.path][end]`. (This workaround should be reverted after upgrading to a patched version of ViewVC, else changed path names will be doubly escaped.)","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2023-22456","url":"https://www.suse.com/security/cve/CVE-2023-22456"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1207008 for CVE-2023-22456","url":"https://bugzilla.suse.com/1207008"}],"title":"SUSE CVE CVE-2023-22456","tracking":{"current_release_date":"2025-07-07T23:53:50Z","generator":{"date":"2023-02-15T03:21:35Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2023-22456","initial_release_date":"2023-02-15T03:21:35Z","revision_history":[{"date":"2023-02-15T03:21:35Z","number":"2","summary":"Current version"},{"date":"2025-01-01T02:16:42Z","number":"3","summary":"Current version"},{"date":"2025-02-14T06:40:53Z","number":"4","summary":"Current version"},{"date":"2025-02-16T06:32:43Z","number":"5","summary":"Current version"},{"date":"2025-07-07T23:53:50Z","number":"6","summary":"Current version"}],"status":"interim","version":"6"}}}
