CVE-2020-15255: CSV injection in Anuko Time Tracker

Noroxi assessment

Priority: Monitor (action score 30/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 3.5% (FIRST EPSS); higher than 89.2% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: anuko timetracker 1.19.23.5325.

Low priority for now. Upgrade to anuko timetracker 1.19.23.5325 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In Anuko Time Tracker before verion 1.19.23.5325, due to not properly filtered user input a CSV export of a report could contain cells that are treated as formulas by spreadsheet software (for example, when a cell value starts with an equal sign). This is fixed in version 1.19.23.5325.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
