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

  - A flaw was found in Samba. The security vulnerability occurs when KDC and the kpasswd service share a     single account and set of keys, allowing them to decrypt each other's tickets. A user who has been     requested to change their password, can exploit this flaw to obtain and use tickets to other services.
    (CVE-2022-2031)

  - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client     had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or     printer) instead of client-supplied data. The client cannot control the area of the server memory written     to the file (or printer). (CVE-2022-32742)

  - A flaw was found in Samba. The KDC accepts kpasswd requests encrypted with any key known to it. By     encrypting forged kpasswd requests with its own key, a user can change other users' passwords, enabling     full domain takeover. (CVE-2022-32744)

  - A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP     add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of samba installed on the remote host is prior to 4.15.9 / 4.16.4. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-208-01 advisory.

  - A flaw was found in Samba. Samba AD users can cause the server to access uninitialized data with an LDAP     add or modify the request, usually resulting in a segmentation fault. (CVE-2022-32745)

  - A flaw was found in the Samba AD LDAP server. The AD DC database audit logging module can access LDAP     message values freed by a preceding database module, resulting in a use-after-free issue. This issue is     only possible when modifying certain privileged attributes, such as userAccountControl. (CVE-2022-32746)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2586-1 advisory.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5205 advisory.

    Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix.
    CVE-2022-2031 Luke Howard reported that Samba AD users can bypass certain restrictions associated with     changing passwords. A user who has been requested to change their password can exploit this to obtain and     use tickets to other services. CVE-2022-32742 Luca Moro reported that a SMB1 client with write access to a     share can cause server memory content to be leaked. CVE-2022-32744 Joseph Sutton reported that Samba AD     users can forge password change requests for any user, resulting in privilege escalation. CVE-2022-32745     Joseph Sutton reported that Samba AD users can crash the server process with a specially crafted LDAP add     or modify request. CVE-2022-32746 Joseph Sutton and Andrew Bartlett reported that Samba AD users can cause     a use-after-free in the server process with a specially crafted LDAP add or modify request. For the stable     distribution (bullseye), these problems have been fixed in version 2:4.13.13+dfsg-1~deb11u5. The fix for     CVE-2022-32745 required an update to ldb 2:2.2.3-2~deb11u2 to correct the defect. We recommend that you     upgrade your samba packages. For the detailed security status of samba please refer to its security     tracker page at: https://security-tracker.debian.org/tracker/samba

A user who has been     requested to change their password, can exploit this flaw to obtain and use tickets to other services.
