Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 1.60% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs OpenSSL OpenSSL and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 30 daysRemediation target: Within 180 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Summary
Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before treating it as a PBMParameter. A crafted message can contain a parameter of a different type, which is then dereferenced as an invalid pointer. Impact summary: A remote, unauthenticated attacker can crash an application acting as a CMP server that accepts PBM-protected messages, or a CMP client talking to a malicious or intercepted CMP server, resulting in a Denial of Service. CWE: CWE-476: NULL Pointer Dereference Description: When verifying the password-based MAC protection of a CMP message, OpenSSL library reads the protectionAlg algorithm parameter with X509_ALGOR_get0(), which returns both the parameter type and its value pointer. The value is then cast to an ASN1_STRING and treated as the expected PBMParameter after only checking that pointer is not NULL. The parameter type returned by X509_ALGOR_get0() was never consulted. This happens during protection verification, before any MAC is computed, so no knowledge of the PBM shared secret is required; the only precondition is that PBM verification is reachable. On the server side this is reached from OSSL_CMP_SRV_process_request() for any application that stands up a CMP server accepting PBM-protected messages, and on the client side from CMP response validation against a malicious or on-path (MITM) server. The reliable consequence is a denial of service; there is no memory disclosure, no controlled memory write, and no path to code execution. CMP is a specialized feature that an application must explicitly enable. FIPS impact: no As the CMP code lives outside the FIPS module boundary, no FIPS modules are affected by this CVE.

Summary
A flaw was found in OpenSSL. A crafted CMP (Certificate Management Protocol) message can cause an invalid pointer dereference due to a missing type check in the password-based protection verification. A remote, unauthenticated attacker can crash applications acting as a CMP server or client, resulting in a denial of service.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

JVN iPedia · Japanese · JVNDB-2026-033250OpenSSL ProjectのOpenSSLにおけるNULL ポインタデリファレンスに関する脆弱性

問題の概要: OpenSSLのCMPパスワードベース保護の検証では、protectionAlgパラメータがNULLでないことのみを確認し、そのASN.1タイプは検証せず、PBMParameterとして扱っています。悪意を持って作成されたメッセージは、異なるタイプのパラメータを含むことができ、その後不正なポインタとして参照される可能性があります。影響の概要: リモートの認証されていない攻撃者が、PBM保護されたメッセージを受け入れるCMPサーバーとして動作するアプリケーション、または悪意のあるもしくは傍受されたCMPサーバーと通信するCMPクライアントをクラッシュさせることができ、その結果サービス拒否（DoS）を引き起こします。CWE: CWE-476: NULLポインタ参照説明: CMPメッセージのパスワードベースMAC保護を検証する際、OpenSSLライブラリはX509_ALGOR_get0()を使ってprotectionAlgアルゴリズムパラメータを読み取ります。この関数はパラメータのタイプとその値のポインタの両方を返します。値はASN1_STRINGにキャストされ、ポインタがNULLでないことだけを確認した後に期待されるPBMParameterとして扱われます。X509_ALGOR_get0()によって返されたパラメータタイプは一切参照されていません。この処理は保護検証中のMACの計算前に行われるため、PBM共有秘密の知識は必要ありません。唯一の前提条件はPBM検証が到達可能であることです。サーバー側では、これはPBM保護メッセージを受け入れるCMPサーバーを立てる任意のアプリケーションのOSSL_CMP_SRV_process_request()から到達され、クライアント側では悪意あるまたは経路上の（MITM）サーバーに対するCMP応答検証から到達されます。確実な結果はサービス拒否であり、メモリの漏洩や制御されたメモリ書き込み、コード実行への経路は存在しません。CMPは明示的にアプリケーションが有効化しなければならない特殊な機能です。FIPSへの影響: ありません。CMPコードはFIPSモジュールの境界外に存在するため、このCVEはFIPSモジュールには影響を及ぼしません。
