CVE-2013-6859
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 · uneditedSAP Sybase Adaptive Server Enterprise (ASE) before 15.0.3 ESD#4.3. 15.5 before 15.5 ESD#5.3, and 15.7 before 15.7 SP50 or 15.7 SP100 does not properly perform authorization, which allows remote authenticated users to gain privileges via unspecified vectors.
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 confidenceSAP Sybase Adaptive Server Enterprise (ASE) contains an authorization bypass vulnerability allowing remote authenticated users to gain elevated privileges through unspecified vectors. The flaw affects versions prior to 15.0.3 ESD#4.3, 15.5 prior to ESD#5.3, and 15.7 before SP50 or SP100.

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 Sybase ASE versionExecute the version query command for your Sybase ASE installation (such as 'select @@version' or 'sp_version' via isql) to retrieve the installed version numberAffected if The version displayed is 15.0.3, 15.5, or 15.7, or any version prior to 15.0.3 ESD#4.3, 15.5 ESD#5.3, or 15.7 SP50/SP100 respectively
-
Compare version against affected rangesMatch your installed version string against the vulnerable ranges: 15.0.x versions before ESD#4.3, 15.5.x versions before ESD#5.3, and 15.7.x versions before SP50 or SP100Affected if Your installed version falls within any of these pre-patch ranges
-
Determine if remote authentication is enabledInspect the Sybase ASE server configuration for remote login permissions and network interfaces (check the interfaces file or sql.ini and review the 'allow remote login' setting)Affected if Remote logins are enabled and the server accepts remote authenticated connections
-
Audit for privilege escalationReview system tables syslogins, sysroles, and srpauth for any unexpected grants of roles, especially the 'sa_role', to non-administrator accountsAffected if Unexpected elevated privileges exist for remote authenticated users that were not intentionally granted
You are affected if your Sybase ASE version is 15.0.3, 15.5, or 15.7 (or earlier) and remote authenticated users can connect to the server.

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 SAP Sybase ASE to version 15.0.3 ESD#4.3 or later, 15.5 ESD#5.3 or later, or 15.7 SP50/SP100 or later. Apply the appropriate patch per your version branch and verify the authorization controls function correctly post-upgrade.
