ITarian SaaS platform / on-premise: Incorrect Permission Assignment for Critical Resource

CVE-2022-25151 is a high-severity incorrect permission assignment for critical resource vulnerability in ITarian SaaS platform / on-premise from Itarian, with a CVSS 3.1 base score of 7.5 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 6.35.37347.20040 as the first without the flaw, so updating ITarian SaaS platform / on-premise to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.83% chance of exploitation within 30 days, higher than 58% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update ITarian SaaS platform / on-premise to 6.35.37347.20040 or a later version.
  2. Update on-premise to 6.35.37347.20040 or a later version.
  3. Update saas_service_desk to 6.35.37347.20040 or a later version.
  4. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Within the Service Desk module of the ITarian platform (SAAS and on-premise), a remote attacker can obtain sensitive information, caused by the failure to set the HTTP Only flag. A remote attacker could exploit this vulnerability to gain access to the management interface by using this vulnerability in combination with a successful Cross-Site Scripting attack on a user.

The underlying weakness: Incorrect Permission Assignment for Critical Resource

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

How developers prevent this class of flaw

  • When using a critical resource such as a configuration file, check to see if the resource has insecure permissions (such as being modifiable by any regular user), and generate an error or even exit the software if there is a possibility that the resource could have been modified by an unauthorized party.
  • Divide the software into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully defining distinct user groups, privileges, and/or roles. Map these against data, functionality, and the related resources. Then set the permissions accordingly. This will allow you to maintain more fine-grained control over your resources.
  • During program startup, explicitly set the default permissions or umask to the most restrictive setting possible. Also set the appropriate permissions during program installation. This will prevent you from inheriting insecure permissions from any user who installs or runs the program.
