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 · unedited
A vulnerability in the inter-service communication of Cisco AnyConnect Secure Mobility Client for Android could allow an unauthenticated, local attacker to perform a service hijack attack on an affected device or cause a denial of service (DoS) condition. The vulnerability is due to the use of implicit service invocations. An attacker could exploit this vulnerability by persuading a user to install a malicious application. A successful exploit could allow the attacker to access confidential user information or cause a DoS condition on the AnyConnect application.

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 confidence

The vulnerability stems from Cisco AnyConnect for Android using implicit service invocations for inter-process communication. This allows a malicious app installed on the same device to intercept or hijack the AnyConnect service by responding to implicit intent broadcasts meant for the legitimate service. An attacker can thus access sensitive VPN communication data or crash the AnyConnect application.

MitigationUsers should avoid installing applications from untrusted sources to prevent the attack vector. The vendor fix requires changing Android service declarations from implicit to explicit intents, ensuring only the legitimate AnyConnect component can respond to service calls.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Cisco AnyConnect is installed
    Check your Android device's installed applications list for 'Cisco AnyConnect' or 'Cisco AnyConnect Secure Mobility Client'
    Affected if AnyConnect is not present on the device, then this CVE does not apply
  2. Check the installed AnyConnect version
    Go to AnyConnect app info on Android and view the version number under 'App version' or 'Version info'
    Affected if The version number is less than 4.8.00826 (for example, 4.8.00790, 4.7.x, etc.)
  3. Compare version against vendor scope
    If version is shown as a build number (such as 4.8.00826), confirm it is lower than 4.8.00826
    Affected if Build number is lower than 4.8.00826, the application uses vulnerable implicit intent handling and is affected by this CVE

You are affected if Cisco AnyConnect Secure Mobility Client for Android is installed with a version number or build number lower than 4.8.00826.
