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
An Open Redirect vulnerability located in the webserver affects several Bosch hardware and software products. The vulnerability potentially allows a remote attacker to redirect users to an arbitrary URL. Affected hardware products: Bosch DIVAR IP 2000 (vulnerable versions: 3.10; 3.20; 3.21; 3.50; 3.51; 3.55; 3.60; 3.61; 3.62; fixed versions: 3.62.0019 and newer), Bosch DIVAR IP 5000 (vulnerable versions: 3.10; 3.20; 3.21; 3.50; 3.51; 3.55; 3.60; 3.61; 3.62; fixed versions: 3.80.0033 and newer). Affected software products: Video Recording Manager (VRM) (vulnerable versions: 3.20; 3.21; 3.50; 3.51; 3.55; 3.60; 3.61; 3.62; fixed versions: 3.70.0056 and newer; 3.81.0032 and newer), Bosch Video Management System (BVMS) (vulnerable versions: 3.50.00XX; 3.55.00XX; 3.60.00XX; fixed versions: 7.5; 3.70.0056).

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

An open redirect vulnerability exists in the webserver component of multiple Bosch video surveillance products (DIVAR IP 2000, DIVAR IP 5000, VRM, and BVMS). Attackers can craft malicious URLs that appear to originate from the legitimate Bosch webserver but redirect users to arbitrary external sites, enabling phishing and credential theft attacks.

MitigationUpdate affected products to the vendor-specified fixed versions: DIVAR IP 2000 to 3.62.0019+, DIVAR IP 5000 to 3.80.0033+, VRM to 3.70.0056+ or 3.81.0032+, and BVMS to 7.5 or 3.70.0056+. If patching is not immediately feasible, implement URL validation at upstream proxies or network perimeter devices to detect and block suspicious redirect parameters.

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 the Bosch product in your environment
    Access the system information page of your Bosch video surveillance system through the web interface or check system documentation to determine if you are running DIVAR IP 2000, DIVAR IP 5000, Video Management System (BVMS), or Video Recording Manager (VRM).
    Affected if The product is any of these four affected products and you cannot confirm the exact version.
  2. Locate the firmware or software version
    Log into the Bosch web interface and navigate to the System Information or About page. For DIVAR IP devices, check the firmware version displayed in the admin dashboard. For BVMS and VRM, check the software version in the application or installer information.
    Affected if You cannot determine the exact installed version number.
  3. Compare your version against affected ranges
    For DIVAR IP 2000: verify if version is below 3.62.0019. For DIVAR IP 5000: verify if version is below 3.80.0033. For BVMS: verify if version is below 3.71.0056. For VRM: verify if version is below 3.70.0056 OR between 3.81.0000 and 3.81.0031.
    Affected if Your installed version falls within any of these vulnerable ranges.
  4. Test for open redirect behavior
    If you cannot confirm a safe version, send a crafted request to your webserver with a redirect parameter pointing to an external domain, such as `https://<your-bosch-server>/redirect?url=https://evil.com`. Observe if the response includes a Location header directing to the external domain.
    Affected if The server returns a 3xx redirect to an external domain not under your organizational control.

You are affected if your Bosch video surveillance product is one of the four affected types AND the installed firmware/software version falls below the fixed version thresholds, or you can demonstrate the open redirect behavior through testing.
