Camera Firmware: Out-of-bounds Read
CVE-2024-11131 is a critical-severity out-of-bounds read vulnerability in Camera Firmware from Synology, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.2.0-0525 as the first without the flaw, so updating Camera Firmware to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.77% chance of exploitation within 30 days, higher than 56% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Camera Firmware to 1.2.0-0525 or a later version.
- Update Tc500 Firmware to 1.2.0-0525 or a later version.
- Update Cc400w Firmware to 1.2.0-0525 or a later version.
- Read the advisory on synology.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.
