CVE-2023-6057
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 vulnerability has been discovered in Bitdefender Total Security HTTPS scanning functionality that results in the improper trust of certificates issued using the DSA signature algorithm. The product does not properly check the certificate chain, allowing an attacker to establish MITM SSL connections to arbitrary sites using a DSA-signed certificate.
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 confidenceBitdefender Total Security's HTTPS scanning functionality improperly trusts certificates signed with the DSA signature algorithm by failing to properly validate the certificate chain. This allows an attacker with a DSA-signed certificate to perform man-in-the-middle (MITM) attacks on SSL connections, intercepting encrypted traffic to arbitrary websites.

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.
-
Check Bitdefender Total Security versionOpen Bitdefender main interface, go to Settings > About, or run 'bdstat --version' from command line to retrieve the installed build numberAffected if Version is lower than 27.0.25.115
-
Verify HTTPS scanning is enabledOpen Bitdefender > Protection > Web Protection > Settings, confirm 'Scan SSL' or 'HTTPS scanning' toggle is enabledAffected if HTTPS scanning feature is turned on (the vulnerability only applies when this is enabled)
-
Confirm DSA certificate validation gapThis requires manual verification by examining SSL inspection behavior; no direct CLI check exists - the version check in step 1 is the primary indicatorAffected if Running vulnerable version (below 27.0.25.115) with HTTPS scanning active
You are affected if Bitdefender Total Security is installed at a version below 27.0.25.115 and HTTPS/SSL scanning protection is enabled.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped27.0.25.115
Apply vendor-supplied patches from Bitdevender when available; in the interim, consider disabling HTTPS scanning or implementing additional network-level SSL inspection controls as compensating measures.
27.0.25.115
- Check the current version of Bitdefender Total Security installed on the system
- Download and install Bitdefender Total Security version 27.0.25.115 or later from the official Bitdefender website or through the product's built-in update mechanism
- Verify that the installed version is 27.0.25.115 or higher
