MITRE ATT&CK Enterprise Techniques

T1550.004 Web Session Cookie Lateral Movement
Adversaries can use stolen session cookies to authenticate to web applications and services.
T1185 Browser Session Hijacking Collection
Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.
T1539 Steal Web Session Cookie Credential Access
An adversary may steal web application or service session cookies and use them to gain access to web applications or Internet services as an authenticated user without needing credentials.
T1550 Use Alternate Authentication Material Lateral Movement
Adversaries may use alternate authentication material, such as password hashes, Kerberos tickets, and application access tokens, in order to move laterally within an environment and bypass normal system access controls.

Mitigating Controls

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-04 full match
prevents

Cookies commonly carry identity assertions; requiring their protection, conveyance, and verification directly eliminates the weakness.

PR.AA-03 mostly match
prevents

Strong authentication mechanisms reduce reliance on unvalidated cookies for identity and access decisions.

PR.DS-02 mostly match
prevents

Cryptographic integrity for data-in-transit directly mitigates tampering of cookies sent over the network.

PR.AA-05 partial match
prevents

Enforcing access policy and least privilege limits damage from cookie misuse but does not address cookie validation itself.

PR.DS-01 partial match
prevents

Integrity protections for data-at-rest can apply to cookie stores but do not cover validation during use.

finds

Security testing can detect cookie-validation flaws but does not itself implement the required controls.

prevents

Application security requirements can mandate cookie validation, integrity protection, and server-side session handling.

prevents

Secure coding practices directly eliminate reliance on unvalidated cookies by requiring proper integrity checks and server-side verification.

prevents

Secure authentication mechanisms can enforce server-side validation and integrity checks that prevent reliance on untrusted cookies.
