CVE-2013-6788
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 · uneditedThe Bitrix e-Store module before 14.0.1 for Bitrix Site Manager uses sequential values for the BITRIX_SM_SALE_UID cookie, which makes it easier for remote attackers to guess the cookie value and bypass authentication via a brute force attack.
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 confidenceThe Bitrix e-Store module before version 14.0.1 generates the BITRIX_SM_SALE_UID cookie using sequential numeric values instead of cryptographically random values. This predictable pattern allows remote attackers to easily guess valid cookie values through brute force, potentially achieving authentication bypass and session hijacking.

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.
-
Verify Bitrix e-Store module installation and versionLocate the Bitrix installation and identify the e-Store module version. This is typically found in the Bitrix admin panel under Module settings, or in the module's version file within the Bitrix directory structure.Affected if The e-Store module version is 14.0.0 or lower.
-
Confirm the version falls within the affected rangeCompare your installed e-Store module version against the known affected range. Versions 14.0.0 and earlier are vulnerable; version 14.0.1 and later contain the fix.Affected if The installed version is 14.0.0 or any version listed as <= 14.0.0.
-
Inspect cookie generation mechanism for predictabilityExamine the code responsible for generating the BITRIX_SM_SALE_UID cookie value. Look for the presence of sequential numeric generation patterns (such as incrementing counters or timestamp-based sequences) instead of cryptographically random values.Affected if The cookie value generation uses sequential or predictable numeric patterns rather than random values.
-
Analyze BITRIX_SM_SALE_UID cookie values for patternsIf possible, observe multiple instances of the BITRIX_SM_SALE_UID cookie over time or across sessions. Check whether the values follow a sequential or easily guessable pattern.Affected if Cookie values increment predictably or follow a sequential pattern.
If the Bitrix e-Store module version is 14.0.0 or lower, the environment is affected by this vulnerability.

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.
From vendor dataUpgrade to Bitrix e-Store module version 14.0.1 or later which implements cryptographically random cookie value generation. As an interim control, implement rate limiting on authentication endpoints and monitor for brute force patterns.
