Security Verify Access Appliance: Inclusion of Functionality from Untrusted Control Sphere

Published Updated By the CyberSecBulletin desk

CVE-2025-36355 is a high-severity inclusion of functionality from untrusted control sphere vulnerability in Security Verify Access Appliance from IBM, with a CVSS 3.1 base score of 8.5 out of 10. It can be exploited with local access to the system by an unauthenticated attacker, without any action from a user. Affected Security Verify Access Appliance versions: 10.0.0.0 through 10.0.9.0 IF2; 11.0.0.0 through 11.0.1.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Security Verify Access to 10.0.9.0 or a later version.
  2. Update Verify Identity Access to 11.0.1.0 or a later version.
  3. Update Verify Identity Access Docker to 11.0.1.0 or a later version.
  4. Read the advisory on ibm.com for workarounds and exact fixed builds.

Official description

IBM Security Verify Access and IBM Security Verify Access Docker 10.0.0.0 through 10.0.9.0 and 11.0.0.0 through 11.0.1.0 could allow a locally authenticated user to execute malicious scripts from outside of its control sphere.

The underlying weakness: Inclusion of Functionality from Untrusted Control Sphere

The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

How developers prevent this class of flaw

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to inbox.txt and ID 2 could map to profile.txt. Features such as the ESAPI AccessReferenceMap provide this capability.
  • For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
