CVE-2021-26961
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 remote unauthenticated cross-site request forgery (csrf) vulnerability was discovered in Aruba AirWave Management Platform version(s): Prior to 8.2.12.0. A vulnerability in the AirWave web-based management interface could allow an unauthenticated remote attacker to conduct a CSRF attack against a vulnerable system. A successful exploit would consist of an attacker persuading an authorized user to follow a malicious link, resulting in arbitrary actions being carried out with the privilege level of the targeted user.
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 confidenceA cross-site request forgery (CSRF) vulnerability in Aruba AirWave Management Platform versions prior to 8.2.12.0 allows unauthenticated remote attackers to exploit the lack of anti-CSRF tokens in the web interface. Attackers trick authenticated users into clicking malicious links, causing the user's browser to execute unauthorized actions with the targeted user's privileges.

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 installed AirWave versionAccess the AirWave management console or check the software version through the system administration interface. Typically found under 'System' > 'Management' or by viewing the login page footer which often displays the version number.Affected if The displayed version number is lower than 8.2.12.0 (for example, 8.2.11.0, 8.2.10.0, etc.)
-
Confirm the web interface is activeVerify that the AirWave web management interface is accessible and running. This is typically accessible on port 443 or 8080 via HTTPS.Affected if The web interface is accessible and the version check from step 1 shows a version below 8.2.12.0
-
Check for CSRF token presence in web formsInspect the HTML source of any AirWave web page (login page or authenticated pages). Look for hidden form fields named 'csrf_token', 'csrf', or similar anti-CSRF mechanisms within the form tags.Affected if No anti-CSRF token field is found in the HTML forms AND the version is below 8.2.12.0
You are affected if the installed AirWave version is below 8.2.12.0 and the web interface lacks anti-CSRF tokens in its forms.
