CVE-2024-21059
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVulnerability in the Oracle Solaris product of Oracle Systems (component: Utility). The supported version that is affected is 11. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Solaris executes to compromise Oracle Solaris. While the vulnerability is in Oracle Solaris, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in takeover of Oracle Solaris. CVSS 3.1 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceLocal privilege escalation vulnerability in Oracle Solaris 11 Utility component. Allows low-privileged user with local system access to escalate privileges and potentially compromise the OS and connected products due to scope change. High impact on confidentiality, integrity, and availability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the operating system versionRun 'uname -a' or 'cat /etc/release' to confirm the OS is Oracle Solaris 11Affected if The system is running Oracle Solaris 11 and has not been patched since April 2024
-
Verify the Solaris 11 utility component is presentIdentify which Solaris utility components are installed. Check for the presence of utilities in /usr/bin or /usr/sbin that may be part of the vulnerable component. Use 'pkginfo' or 'pkg list' to enumerate installed packages.Affected if The vulnerable utility component from Oracle Solaris 11 is installed and the system is unpatched
-
Check for applied security patchesRun 'showrev -p' to list all applied patches. Compare against Oracle's April 2024 Critical Patch Update for Solaris 11.Affected if No Oracle April 2024 security patches for Solaris 11 have been applied, or the specific patch for CVE-2024-21059 is missing
-
Verify user privilege levelsCheck if low-privileged local user accounts exist using 'getent passwd' or 'id' commands. Review /etc/user_attr for extended user attributes.Affected if Low-privileged local user accounts exist on the unpatched Oracle Solaris 11 system, creating the condition for privilege escalation
A system is affected if it runs unpatched Oracle Solaris 11 and contains low-privileged local user accounts that could be exploited for privilege escalation through the vulnerable utility component.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply Oracle's April 2024 security patches for Oracle Solaris 11. Until patched, restrict physical and logical access to Solaris systems, limit privileged accounts, and monitor for suspicious local user activity.
