CVE-2023-39513 is a medium-severity cross-site scripting vulnerability in Cacti Cacti, published on 5 Sep 2023. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link. ### Official description Cacti is an open source operational monitoring and fault management framework. Affected versions are subject to a Stored Cross-Site-Scripting (XSS) Vulnerability which allows an authenticated user to poison data stored in the _cacti_'s database. These data will be viewed by administrative _cacti_ accounts and execute JavaScript code in the victim's browser at view-time. The script under `host.php` is used to monitor and manage hosts in the _cacti_ app, hence displays useful information such as data queries and verbose logs. _CENSUS_ found that an adversary that is able to configure a data-query template with malicious code appended in the template path, in order to deploy a stored XSS attack against any user with the _General Administration>Sites/Devices/Data_ privileges. A user that possesses the _Template Editor>Data Queries_ permissions can configure the data query template path in _cacti_. Please note that such a user may be a low privileged user. This configuration occurs through `http:///cacti/data_queries.php` by editing an existing or adding a new data query template. If a template is linked to a device then the formatted template path will be rendered in the device's management page, when a _verbose data query_ is requested. This vulnerability has been addressed in version 1.2.25. Users are advised to upgrade. Users unable to update should manually filter HTML output.

What it is: CVE-2023-39513 is a medium-severity cross-site scripting vulnerability in Cacti Cacti, published on 5 Sep 2023. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link. Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-39513 exists. Affected product: Cacti Cacti. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
