When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate.

According to the versions of the curl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dla-3951 advisory.

    Package        : curl     Version        : 7.74.0-1.3+deb11u14     CVE ID         : CVE-2024-8096


    curl a command line tool for transferring data with URL syntax was     affected by CVE-2024-8096. When the TLS backend is GnuTLS, curl may     incorrectly handle OCSP stapling. If the OCSP status reports an error     other than revoked (e.g., unauthorized), it is not treated as a     bad certificate, potentially allowing invalid certificates to be     considered valid.

    For Debian 11 bullseye, this problem has been fixed in version     7.74.0-1.3+deb11u14.

    We recommend that you upgrade your curl packages.

    For the detailed security status of curl please refer to     its security tracker page at:

    libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time     field.If given an syntactically incorrect field, the parser might end up using -1 for the length of the
    *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not     (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents     getting returned to the application when     [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used.(CVE-2024-7264)

According to its self-reported version, the Nessus Network Monitor running on the remote host is prior to 6.5.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2024-17 advisory.

  - Nessus Network Monitor leverages third-party software to help provide underlying functionality. Several of     the third-party components (OpenSSL, expat, curl, and libxml2)were found to contain vulnerabilities,     and updated versions have been made available by the providers.Out of caution and in line with best     practice, Tenable has opted to upgrade these components to address the potential impact of the issues.
    Nessus Network Monitor 6.5.0 updates OpenSSL to version 3.0.15, expat to version 2.6.3, curl to version     8.10.0, and libxml2 to to version 2.13.1 to address the identified vulnerabilities.Additionally, one     separate vulnerability was discovered, reported and fixed:A stored cross site scripting vulnerability     exists in Nessus Network Monitor where an authenticated, privileged local attacker could inject arbitrary     code into the NNM UI via the local CLI. - CVE-2024-9158 Tenable has released Nessus Network Monitor 6.5.0     to address these issues. The installation files can be obtained from the Tenable Downloads Portal     (https://www.tenable.com/downloads/nessus-network-monitor).
