ServiceNow Incomplete List of Disallowed Inputs
CVE-2024-5217 is a critical-severity incorrect comparison vulnerability in Now Platform from ServiceNow, 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 versions Utah Patch 10 Hot Fix 3, Utah Patch 10a Hot Fix 2, Utah Patch 10b Hot Fix 1 as the first without the flaw, so updating Now Platform to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on July 29, 2024, which means attacks have been observed in the wild.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Update Now Platform to Utah Patch 10 Hot Fix 3 or Utah Patch 10a Hot Fix 2 or Utah Patch 10b Hot Fix 1 or Vancouver Patch 6 Hot Fix 2, whichever matches your release line, or a later version.
- Update servicenow to utah_patch_10_hot_fix_3 or utah_patch_10a_hot_fix_2 or utah_patch_10b_hot_fix_1 or vancouver_patch_6_hot_fix_2, whichever matches your release line, or a later version.
- CISA's required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- Read the advisory on support.servicenow.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.
