Summary

CVE-2025-9384 is a low-severity Improper Resource Shutdown or Release (CWE-404) vulnerability in Broadcom Tcpreplay. Its CVSS base score is 1.9 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 16th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-2 (Flaw Remediation) and CM-6 (Configuration Settings) — see the control section below for these in your framework.

Vulnerability Data

A vulnerability was detected in appneta tcpreplay up to 4.5.1. Impacted is the function tcpedit_post_args of the file /src/tcpedit/parse_args.c. The manipulation results in null pointer dereference. The attack is only possible with local access. The exploit is now public and…

MITRE ATT&CK Enterprise TechniquesAI

T1499.004 Application or System Exploitation Impact
Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users.
Why these techniques?

Local null pointer dereference enables application crash/DoS via exploitation of the vulnerable binary.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly addresses the publicly disclosed null-pointer flaw by requiring prompt application of the vendor-supplied upgrade to 4.5.2-beta2.

preventdetect

Enforces approved software versions and configuration settings so that only the patched tcpreplay binary is present on the system.

prevent

Limits execution of the vulnerable tcpreplay binary to the fewest accounts possible, reducing the local attack surface.

Secure SDLC practices directly include coding standards for correct resource allocation and release.

Runtime monitoring can detect resource exhaustion caused by improper shutdown or release.

ID.AM-08 partial match
prevents

Lifecycle management of assets can encompass proper resource release at end-of-life or shutdown.

PR.IR-04 partial match
prevents

Capacity management helps surface leaks from unreleased resources but does not prevent the coding flaw.

detects

Security testing can detect NULL dereference defects before release.

prevents

Including restart, recovery and media-handling instructions reduces the likelihood that resources or sensitive data will be left in an exposed or improperly released state after a failure.

prevents

Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.

prevents

Application security requirements can specify input validation and pointer-safety rules.

prevents

Secure architecture principles encourage defensive design that avoids unsafe pointer use.

prevents

Secure coding standards directly require NULL-pointer checks and safe dereference patterns.
