TIBCO Hawk: Improper Restriction of XML External Entity Reference
CVE-2024-10218 is a critical-severity improper restriction of XML external entity reference vulnerability in TIBCO Hawk from TIBCO Software, with a CVSS 4.0 base score of 9.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. The record lists version 5 as the first without the flaw, so updating TIBCO Hawk to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.49% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update TIBCO Hawk to 5 or a later version.
- Update TIBCO Operational Intelligence to 0 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
