CVE-2021-33394: Cubecart 6.4.2 allows Session Fixation.

Cubecart 6.4.2 allows Session Fixation. The application does not generate a new session cookie after the user is logged in. A malicious user is able to create a new session cookie value and inject it to a victim. After the victim logs in, the injected cookie becomes valid, giving the attacker access to the user's account through the active session.

Security readout for executives and security teams

Plain-English summary

CubeCart 6.4.2 could let an attacker take over a user session if the victim logs in with a session cookie value the attacker influenced. The core issue is that the application did not issue a fresh session cookie after login.

Executive priority

Treat this as a targeted account-takeover risk for affected CubeCart stores. Prioritize remediation where administrator access, customer accounts, or payment-related workflows are exposed.

Technical view

This is a session fixation flaw in CubeCart 6.4.2. Authentication did not regenerate the session identifier, so a session value established before login could remain valid after authentication and be reused to access the victim’s account session.

Likely exposure

Exposure is most likely on internet-facing CubeCart 6.4.2 stores with customer or administrator login flows. The source bundle does not provide CPEs, broader affected version ranges, or deployment-specific exposure data.

Exploitation context

The bundle includes a public proof-of-concept reference and a CubeCart commit reference. It does not show CISA KEV listing or other cited evidence of active exploitation.

Researcher notes

Evidence is limited but coherent: the CVE description identifies CubeCart 6.4.2 and the failure to regenerate session cookies after login, with a public PoC reference and vendor commit reference. No CVSS, CWE, CPE, or KEV evidence is provided.

Mitigation direction

  • Identify any CubeCart 6.4.2 deployments.
  • Check CubeCart guidance for a release containing the referenced fix.
  • Ensure login regenerates the session identifier after successful authentication.
  • Expire existing sessions after remediation where operationally practical.

Validation and detection

  • Confirm the application version for every CubeCart deployment.
  • Verify session identifiers rotate after successful login.
  • Check whether the referenced vendor commit or equivalent fix is present.
  • Review logs for suspicious concurrent use of the same session.
