ADAM-5630: Use of Persistent Cookies Containing Sensitive Information
CVE-2024-39275 is a high-severity use of persistent cookies containing sensitive information vulnerability in ADAM-5630 from Advantech, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version v2.5.2 as the first without the flaw, so updating ADAM-5630 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.41% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update ADAM-5630 to v2.5.2 or a later version.
- Update adam-5630_firmware to 2.5.2 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Cookies of authenticated Advantech ADAM-5630 users remain as active valid cookies when a session is closed. Forging requests with a legitimate cookie, even if the session was terminated, allows an unauthorized attacker to act with the same level of privileges of the legitimate user.
