Summary

CVE-2024-1947 is a medium-severity Data Amplification (CWE-409) vulnerability in Gitlab Gitlab. Its CVSS base score is 4.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked at the 40th 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 SI-10 (Information Input Validation) and SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation can reject or limit decompression of data whose expansion ratio exceeds safe thresholds.

SC-5 Denial-of-service Protection partial match

DoS protection limits the resource-exhaustion impact when a decompression bomb is processed.

SC-6 Resource Availability partial match

Resource allocation controls bound memory/CPU consumption that a data-amplification attack would otherwise exhaust.

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.

DE.CM-09 partial match
blocks

Runtime monitoring of compute resources can detect exhaustion caused by decompression bombs.

PR.IR-04 partial match
blocks

Capacity planning and monitoring directly limits the availability impact of data-amplification attacks.

PR.PS-06 partial match
blocks

Secure-development practices include input-validation and resource-limit checks that prevent improper handling of compressed data.

A.8.25 Secure development life cycle partial match
blocks

Secure development lifecycle includes input validation and resource-limit checks that mitigate data-amplification attacks.

A.8.26 Application security requirements partial match
blocks

Application security requirements can mandate limits on decompression size and ratio.

A.8.27 Secure system architecture and engineering principles partial match
blocks

Secure architecture principles encourage defensive design against resource-exhaustion threats.
