CVE-2020-8026
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 · uneditedA Incorrect Default Permissions vulnerability in the packaging of inn in openSUSE Leap 15.2, openSUSE Tumbleweed, openSUSE Leap 15.1 allows local attackers with control of the new user to escalate their privileges to root. This issue affects: openSUSE Leap 15.2 inn version 2.6.2-lp152.1.26 and prior versions. openSUSE Tumbleweed inn version 2.6.2-4.2 and prior versions. openSUSE Leap 15.1 inn version 2.5.4-lp151.3.3.1 and prior versions.
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 confidenceThe inn (InterNetNews) package in openSUSE distributions has incorrect default permissions on certain files or directories. This allows a local user with basic access to escalate privileges to root by exploiting these overly permissive file permissions.

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.
-
Verify inn package installationRun 'rpm -q inn' or check for inn binaries such as 'innd' or 'inn.conf' in the systemAffected if inn package is not installed means not affected
-
Determine installed inn versionRun 'rpm -q --qf "%{VERSION}-%{RELEASE}" inn' or check the installed inn package version against the affected ranges: openSUSE Backports SLE 15.0, openSUSE Tumbleweed <= 2.6.2-4.2, openSUSE Leap 15.1 and 15.2Affected if installed version falls within any of the affected version ranges indicates potential vulnerability
-
Inspect inn configuration directory permissionsCheck permissions on /etc/inn/ or /etc/news/ directory using 'ls -la /etc/inn/' or 'ls -la /etc/news/'Affected if configuration directory or files within it are writable by non-root users indicates the vulnerability is present
-
Inspect inn binary permissionsCheck permissions on inn binaries in /usr/sbin/ or /usr/bin/ using 'ls -la /usr/sbin/inn*' or 'ls -la /usr/bin/inn*'Affected if binaries are world-writable or owned by unprivileged user indicates exploitable condition
-
Inspect inn data and log directory permissionsCheck permissions on /var/lib/news/, /var/news/, or /var/log/news/ using 'ls -la /var/lib/news/' or similar pathsAffected if data directories or log files are writable by basic users indicates the permission flaw exists
User is affected if inn package is installed AND version matches affected ranges AND inn configuration/data files or directories have overly permissive (world-writable) permissions accessible to unprivileged local users.

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 the vendor-supplied patch or update that corrects the default permissions on inn package files/directories to restrict access appropriately, preventing unprivileged local users from modifying sensitive files.
