Vulnerability discussion

DBMSs utilize sessions and session identifiers to control application behavior and user access. If an attacker can guess the session identifier or can inject or manually insert session information, the session may be compromised.This requirement focuses on communications protection for the DBMS session rather than for the network packet. The intent of this control is to establish grounds for confidence at each end of a communications session in the ongoing identity of the other party and in the validity of the information being transmitted. The DBMS must recognize only system-generated session identifiers. If an attacker were able to generate a session with a non-system-generated session identifier and have it recognized by the system, the attacker could gain access to the system without passing through access controls designed to limit database sessions to authorized users.

Check content

Review DBMS settings and vendor documentation to determine whether the DBMS recognizes session identifiers that are not system-generated. If the DBMS recognizes session identifiers that are not system generated, this is a finding.

Fix text

Utilize a DBMS product that only recognizes session identifiers that are system-generated.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
