CVE-2020-15297
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 · uneditedInsufficient validation in the Bitdefender Update Server and BEST Relay components of Bitdefender Endpoint Security Tools versions prior to 6.6.20.294 allows an unprivileged attacker to bypass the in-place mitigations and interact with hosts on the network. This issue affects: Bitdefender Update Server versions prior to 6.6.20.294.
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 · moderate confidenceInsufficient validation in the Bitdefender Update Server and BEST Relay components of Bitdefender Endpoint Security Tools allows unprivileged attackers to bypass in-place security mitigations and interact with hosts on the network, enabling potential lateral movement.

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 installed Bitdefender Endpoint Security Tools versionLocate the Bitdefender Endpoint Security Tools installation and retrieve the product version information. This can typically be found in the program's properties, the installed software list, or by running the product's version check command if available.Affected if The installed version is lower than 6.6.20.294 (for example, 6.5.x, 6.6.0 through 6.6.20.293, or any earlier major version).
-
Determine if the Update Server component is enabledCheck whether the Bitdefender Update Server component is configured or running within the Bitdefender Endpoint Security Tools installation. This component is typically managed through the product's administrative console or configuration settings.Affected if The Update Server component is present and enabled on the system, and the product version is below 6.6.20.294.
-
Determine if the BEST Relay component is enabledCheck whether the BEST Relay component is configured or running within the Bitdefender Endpoint Security Tools installation. This component is typically managed through the product's administrative console or configuration settings.Affected if The BEST Relay component is present and enabled on the system, and the product version is below 6.6.20.294.
-
Verify component version if availableIf the Update Server or BEST Relay components have their own version information, retrieve and compare it against the affected range.Affected if Any Update Server or BEST Relay component version is below the fixed version associated with 6.6.20.294.
The environment is affected if Bitdefender Endpoint Security Tools version is lower than 6.6.20.294 and either the Update Server or BEST Relay component is enabled.
