Source: CVE Database V5
Vendor/Project: Apache Software Foundation
Product: Apache CloudStack

Description

Apache CloudStack versions 4.20.3.0 and 4.22.1.0 contain a vulnerability in SAML authentication where improper verification of cryptographic signatures allows a malicious actor to forge SAML responses. This can enable unauthorized login if the attacker spoofs the IdP IP address or registers a URL with the management server. Fixed versions 4.20.3.1 and 4.22.1.1 address this issue.

Technical Analysis

CVE-2026-68745 describes an improper verification of cryptographic signatures (CWE-347) in the SAML authentication mechanism of Apache CloudStack versions 4.20.3.0 and 4.22.1.0. The flaw allows an attacker who can spoof the Identity Provider's IP address or register a URL with the management server to forge SAML responses, potentially gaining unauthorized access. The vulnerability affects multiple platforms and is resolved by upgrading to versions 4.20.3.1, 4.22.1.1, or later.

Potential Impact

Successful exploitation allows an attacker to bypass authentication by forging SAML responses, leading to unauthorized access with high confidentiality, integrity, and availability impact. This could compromise management server control and sensitive data.

Mitigation Recommendations

Users should upgrade Apache CloudStack to versions 4.20.3.1, 4.22.1.1, or later, where this vulnerability is fixed. No other mitigations are specified. Patch status is confirmed by vendor advisory recommending these upgrades.
