Ibm Datacap 9.1.5 … 9.1.9
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-39734 is a medium-severity Reliance on Cookies without Validation and Integrity Checking (CWE-565) vulnerability in Ibm Datacap. Its CVSS base score is 4.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Web Session Cookie (T1550.004); ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-23 (Session Authenticity) — see the control section below for these in your framework.

Vulnerability Data
IBM Datacap Navigator 9.1.5, 9.1.6, 9.1.7, 9.1.8, and 9.1.9 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by…

planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic. IBM X-Force ID: 296001.

V3.3.1
Mitigating Controls (NIST 800-53 r5) AI
Access Enforcement requires authorizations to be enforced by the system rather than by trusting client-supplied cookie values.
Session Authenticity directly requires protecting the integrity and authenticity of session tokens such as cookies, eliminating blind reliance on them.
Requiring confidentiality protection for transmitted information forces use of HTTPS-only cookies via the Secure attribute, eliminating exposure of sensitive session data.
Software, Firmware, and Information Integrity can detect unauthorized modification of cookie-based data after the fact via integrity verification.
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.
Cookies commonly carry identity assertions; requiring their protection, conveyance, and verification directly eliminates the weakness.
Strong authentication mechanisms reduce reliance on unvalidated cookies for identity and access decisions.
Cryptographic integrity for data-in-transit directly mitigates tampering of cookies sent over the network.
Enforcing hardened configuration baselines includes requiring the Secure flag on sensitive cookies.
Secure SDLC practices explicitly require correct use of security attributes such as the cookie Secure flag.
Enforcing access policy and least privilege limits damage from cookie misuse but does not address cookie validation itself.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect cookie-validation flaws but does not itself implement the required controls.
Use of cryptography control mandates encryption in transit, which HTTPS provides, but does not specifically require the Secure cookie attribute.
Application security requirements can mandate cookie validation, integrity protection, and server-side session handling.
Secure coding practices directly eliminate reliance on unvalidated cookies by requiring proper integrity checks and server-side verification.
Secure authentication mechanisms can enforce server-side validation and integrity checks that prevent reliance on untrusted cookies.
