Vulnerability Data

Jenkins SAML Single Sign On(SSO) Plugin 2.0.2 and earlier does not perform hostname validation when connecting to miniOrange or the configured IdP to retrieve SAML metadata, which could be abused using a man-in-the-middle attack to intercept these connections.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-345 CWE-346

Mandates provision of authenticity and integrity artifacts that enable verification of name/address resolution data.

addresses: CWE-345 CWE-346

Requires explicit verification of data authenticity from authoritative sources, preventing acceptance of unauthenticated resolution responses.

addresses: CWE-346

Requires unique identification of the service before communications, addressing failures to validate the origin of the interaction.

addresses: CWE-345

Directly requires independent verification of matching output before adverse decisions, mitigating insufficient authenticity checks on data from external sources.

addresses: CWE-346

Trusted path establishment enforces validation that the communication originates from and reaches only the intended trusted system components.

addresses: CWE-345

Use of approved PKI certificates provides verifiable data authenticity and origin for communications and artifacts.

addresses: CWE-346

Mandates origin validation so that only legitimate endpoints can continue the authenticated session.

addresses: CWE-345

Control requires verification of data authenticity/integrity (e.g., checksums) after aggregation/packing, directly reducing exploitation of insufficient verification before transmission.

degrades

Network security controls enforce origin validation at network boundaries.

degrades

Security of network services includes validating the authenticity of service endpoints.

blocks

A.8.24's guidance on identifying protection levels, selecting algorithms/strength for authenticity/integrity (items b,f), using cryptography for transmitted/stored data (c), and key management directly stops many CWE-345 exploits by ensuring verifiable authenticity; however, it leaves a bounded remainder where verification logic itself is flawed or absent (e.g. accepting unverified signatures or weak schemes), as the control depends on correct implementation in other mechanisms.

blocks

Secure SDLC incorporates authenticity verification requirements throughout development.

blocks

Application security requirements can mandate data authenticity verification mechanisms.

blocks

A.8.27 mandates security-by-design principles (defense-in-depth, least privilege, assume-breach, distrust-external-input, zero-trust verification) plus design reviews that can catch and block origin-validation gaps in many common cases, but leaves a bounded remainder (e.g. protocol-level or third-party component origin errors not surfaced by the organization's review process).

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-345, a class-level weakness. Rules are authored against its narrower children: CWE-347, CWE-348, CWE-349, CWE-353, CWE-354, CWE-494, CWE-649, CWE-924.
  • No fine-grained STIG row for CWE-346, a class-level weakness, and none of its children carries one either.
