SuiteCRM: Logging of Excessive Data
CVE-2024-36416 is a high-severity logging of excessive data vulnerability in SuiteCRM from Salesagility, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 7.14.4, 8.6.1 as the first without the flaw, so updating SuiteCRM to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.95% chance of exploitation within 30 days, higher than 81% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update SuiteCRM to 7.14.4 or 8.6.1, whichever matches your release line, or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
SuiteCRM is an open-source Customer Relationship Management (CRM) software application. Prior to versions 7.14.4 and 8.6.1, a deprecated v4 API example with no log rotation allows denial of service by logging excessive data. Versions 7.14.4 and 8.6.1 contain a fix for this issue.

The underlying weakness: Logging of Excessive Data
The product logs too much information, making log files hard to process and possibly hindering recovery efforts or forensic analysis after an attack.
How developers prevent this class of flaw
- Suppress large numbers of duplicate log messages and replace them with periodic summaries. For example, syslog may include an entry that states last message repeated X times when recording repeated events.
- Support a maximum size for the log file that can be controlled by the administrator. If the maximum size is reached, the admin should be notified. Also, consider reducing functionality of the product. This may result in a denial-of-service to legitimate product users, but it will prevent the product from adversely impacting the entire system.
- Adjust configurations appropriately when the product is transitioned from a debug state to production.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
