iTop: Files or Directories Accessible to External Parties
CVE-2023-48710 is a critical-severity files or directories accessible to external parties vulnerability in iTop from Combodo, 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 2.7.10, 3.0.4, 3.1.1 as the first without the flaw, so updating iTop to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.72% chance of exploitation within 30 days, higher than 54% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update iTop to 2.7.10 or 3.0.4 or 3.1.1, 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
iTop is an IT service management platform. Files from the `env-production` folder can be retrieved even though they should have restricted access. Hopefully, there is no sensitive files stored in that folder natively, but there could be from a third-party module. The `pages/exec.php` script as been fixed to limit execution of PHP files only. Other file types won't be retrieved and exposed. The vulnerability is fixed in 2.7.10, 3.0.4, 3.1.1, and 3.2.0.
