MISP: Site-Admin Can Repoint Redis Workers to Attacker-Controlled Server via UI/API Configuration Change

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.64% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 50.0% of scored records. A rank, not a probability.
NVD base score
6.9 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

The fix restricts the Redis host settings (MISP.redis_host, Plugin.ZeroMQ_redis_host, SimpleBackgroundJobs.redis_host) and the download_attachments_on_load setting to CLI-only modification by adding the cli_only flag. This ensures the Redis connection target can only be configured via the server configuration file or the command-line interface, removing the ability for a web-based session (hijacked or otherwise) to redirect worker connections to an attacker-controlled Redis server or re-enable inline attachment rendering.
