ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2025-20122-1 advisory.

    - CVE-2025-61984: code execution via control characters in usernames when a ProxyCommand is used     (bsc#1251198).
     - CVE-2025-61985: code execution via '\0' character in ssh:// URI when a ProxyCommand is used     (bsc#1251199).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

An update of the openssh package has been released.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:4067-1 advisory.

    - CVE-2025-61984: Fixed code execution via control characters in usernames when a ProxyCommand is used     (bsc#1251198)
    - CVE-2025-61985: Fixed code execution via '\0' character in ssh:// URI when a ProxyCommand is used     (bsc#1251199)

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

The version of OpenSSH installed on the remote host is prior to 10.1. It is, therefore, affected by multiple vulnerabilities:

  - ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly     untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted     sources are the command line and %-sequence expansion of a configuration file. (A configuration file     that provides a complete literal username is not categorized as an untrusted source.) (CVE-2025-61984)

  - ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a     ProxyCommand is used. (CVE-2025-61985)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code     execution when a ProxyCommand is used. (CVE-2025-61985)

Note that Nessus relies on the presence of the package as reported by the vendor.
