Description

Jenkins SAML Single Sign On(SSO) Plugin Cross-Site Request Forgery vulnerability

Jenkins SAML Single Sign On(SSO) Plugin 2.0.0 and earlier does not perform a permission check in an HTTP endpoint.

This allows attackers with Overall/Read permission to send an HTTP POST request with JSON body containing attacker-specified content, to miniOrange’s API for sending emails.

Additionally, this HTTP endpoint does not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.

SAML Single Sign On(SSO) Plugin 2.0.1 removes the affected HTTP endpoint.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. A user must be tricked into taking some action. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.

Weakness class

CVE-2023-32995 is classified as CWE-352: Cross-Site Request Forgery (CSRF). A state-changing request is accepted without proof it was intended, so another site can trigger it using the victim's session.
