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
Vulnerability in the Oracle Communications Interactive Session Recorder product of Oracle Communications (component: Provision API). The supported version that is affected is 6.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Communications Interactive Session Recorder. While the vulnerability is in Oracle Communications Interactive Session Recorder, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Communications Interactive Session Recorder accessible data as well as unauthorized read access to a subset of Oracle Communications Interactive Session Recorder accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Communications Interactive Session Recorder. CVSS 3.1 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L).

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

Unauthenticated remote attacker can exploit the Provision API in Oracle Communications Interactive Session Recorder 6.4 via HTTP to achieve unauthorized read, write, and delete access to a subset of data, plus partial denial of service. The CVSS vector indicates network-exploitable with no privileges required and no user interaction, affecting all three security properties (confidentiality, integrity, availability).

MitigationApply Oracle's available patch for CVE-2021-2461. If no patch is immediately available, restrict network access to the Provision API via firewall or web application firewall (WAF) rules until the vendor fix can be deployed.

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. Identify installed version of Oracle Communications Interactive Session Recorder
    Locate the installed version of Oracle Communications Interactive Session Recorder in your environment using your system's software inventory or version-checking utilities, then compare it to version 6.4
    Affected if The installed version is exactly 6.4
  2. Confirm Provision API is enabled and exposed
    Check if the Provision API component is enabled in the Oracle Communications Interactive Session Recorder configuration and is accessible via HTTP
    Affected if The Provision API is enabled and reachable over HTTP without authentication
  3. Verify network accessibility of the Provision API endpoint
    Determine whether the Provision API HTTP endpoint is exposed to the network, either externally or internally, by reviewing firewall rules, network configurations, or by testing connectivity to the API port
    Affected if The Provision API HTTP endpoint is network-accessible from an untrusted network segment
  4. Check for unauthorized access indicators
    Review access logs and audit trails for the Provision API endpoint for any requests originating from unauthenticated or unexpected sources that performed read, write, or delete operations
    Affected if Unauthenticated requests to the Provision API are present in logs or unexpected data modifications are detected

A user is affected if they have Oracle Communications Interactive Session Recorder version 6.4 running with the Provision API enabled and exposed over HTTP, allowing unauthenticated network attackers to access or manipulate data.
