CyberRota Analysis

AI-Generated

Snipe-IT versions 8.5.0 through 8.6.3 are vulnerable to an open redirect issue in the SAML assertion-consumer endpoint, allowing unauthenticated attackers to redirect users to arbitrary external URLs post-authentication. This vulnerability poses a risk of credential-harvesting phishing attacks, particularly for deployments utilizing SAML SSO. Organizations using affected versions should prioritize upgrading to version 8.7.0 or later to mitigate this risk.

Original NVD Description

Snipe-IT 8.5.0 through 8.6.3 contains an open redirect vulnerability in its SAML assertion-consumer endpoint (SamlController::acs, POST /saml/acs). The endpoint wrote the RelayState POST parameter directly into Laravel's url.intended session key with only CR/LF characters stripped, and LoginController later issued redirect()->intended(), which passes an absolute URL through to the Location header unchanged. An unauthenticated attacker who induces a user of a SAML-SSO-enabled instance to visit a crafted IdP-initiated SSO link can therefore cause the victim's browser to be redirected to an arbitrary absolute external URL immediately after a successful authentication, which the advisory notes facilitates credential-harvesting phishing. No account on the target instance and no compromise of the identity provider are required. Only deployments with SAML SSO enabled are affected. Fixed in 8.7.0 (commit d30b73d, PR #19386), which validates RelayState via a new Helper::sameOriginUrl check before storing it.
