CVE-2015-5317
Jenkins User Interface (UI) contains an information disclosure vulnerability that allows users to see the names of jobs and builds otherwise inaccessible to them on the "Fingerprints" pages.
What this means for your business
- It affects Jenkins User Interface (UI). It matters if your company, or a supplier that handles your data, runs it.
- Attackers are already using it. CISA added it to its list of flaws used in real attacks on 12 May 2023.
- FIRST's prediction model gives it a 23% chance of attack attempts being seen in the next 30 days, ranking above 97% of all known flaws.
What to do
- 1Check whether your company or your suppliers run Jenkins User Interface (UI).
- 2If you do, follow CISA's required action below. No patch reference has been published yet.
- 3Treat it as urgent. US federal agencies must fix it by 2 June 2023. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
- 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
