Libreswan, via the function RSA_authenticate_hash_signature_pkcs1_1_5_rsa(), did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v1_5 (RFC 8017). A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload when small public exponents are used (e.g., e=3), leading to impersonation. Additionally, a remote attacker, by encoding a shorter than expected hash in the AUTH payload, could trigger an assertion leading to denial-of-service. The daemon aborts and restarts; continued exploitation causes sustained denial of service. Remote code execution is not possible. X.509 certificate verifications of the remote IKE peer are not affected.

The remote Alibaba Cloud Linux 3 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2026:0238 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2026-12413:
    An invalidly formatted IKEv2 fragment causes the Libreswan pluto daemon to crash and restart. Continued     exploitation would cause a denial of service. The function reassemble_v2_incoming_fragments() would ignore     unknown outer payloads but still store these in a fixed size array msg_digest.digest[PAYLIMIT]. An off-by-     one error in the assertion PASSERT(logger, md->digest_roof < elemsof(md->digest)) causes the daemon to     abort. No remote code execution is possible. Any configuration that allows IKEv2 connections that do not     set fragmentation=no are vulnerable. IKEv1 is not affected.

    CVE-2026-14957:

The version of Libreswan installed on the remote host is prior to 5.3.1. It is, therefore, affected by multiple vulnerabilities:

  - Libreswan, via the function RSA_authenticate_hash_signature_raw_rsa(), did not correctly verify the length of the     authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS #1 RSA Encryption as per RFC     2313. A remote attacker can use a variation on the Bleichenbacher attack to forge the SIG payload when small public     exponents are being used (e.g., e=3), which could lead to impersonation. Additionally, a remote attacker, by     encoding a shorter than expected hash in the SIG payload, could trigger an assertion leading to     denial-of-service. (CVE-2026-50721)

  - Libreswan, via the function RSA_authenticate_hash_signature_pkcs1_1_5_rsa(), did not correctly verify the DER     encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v1_5 (RFC 8017). A remote     attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload when small public exponents are     used (e.g., e=3), leading to impersonation. Additionally, a remote attacker, by encoding a shorter than expected     hash in the AUTH payload, could trigger an assertion leading to denial-of-service. (CVE-2026-50722)

The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-50722 advisory.

  - Libreswan, via the function RSA_authenticate_hash_signature_pkcs1_1_5_rsa(), did not correctly verify the     DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v1_5 (RFC     8017). A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload when     small public exponents are used (e.g., e=3), leading to impersonation. Additionally, a remote attacker, by     encoding a shorter than expected hash in the AUTH payload, could trigger an assertion leading to denial-     of-service. The daemon aborts and restarts; continued exploitation causes sustained denial of service.
    Remote code execution is not possible. X.509 certificate verifications of the remote IKE peer are not     affected. (CVE-2026-50722)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
