CVE-2025-51005 7.5 HIGH 1 PoC Analysis EPSS 0.00

A heap-buffer-overflow vulnerability exists in the tcpliveplay utility of the tcpreplay-4.5.1. When a crafted pcap file is processed, the program incorrectly handles memory in the checksum calculation logic at do_checksum_math_liveplay in tcpliveplay.c, leading to a possible denial of service.

CWE-122 Sep 23, 2025

CVE-2025-51006 7.8 HIGH 1 PoC Analysis EPSS 0.00

Within tcpreplay's tcprewrite, a double free vulnerability has been identified in the dlt_linuxsll2_cleanup() function in plugins/dlt_linuxsll2/linuxsll2.c. This vulnerability is triggered when tcpedit_dlt_cleanup() indirectly invokes the cleanup routine multiple times on the same memory region. By supplying a specifically crafted pcap file to the tcprewrite binary, a local attacker can exploit this flaw to cause a Denial of Service (DoS) via memory corruption.

CWE-415 Sep 22, 2025

CVE-2025-9649 3.3 LOW EPSS 0.00

A security vulnerability has been detected in appneta tcpreplay 4.5.1. Impacted is the function calc_sleep_time of the file send_packets.c. Such manipulation leads to divide by zero. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. Upgrading to version 4.5.3-beta3 is recommended to address this issue. It is advisable to upgrade the affected component. The vendor confirms in a GitHub issue reply: "Was able to reproduce in 6fcbf03 but NOT 4.5.3-beta3."

CVE-2025-9384 3.3 LOW EPSS 0.00

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 may be used. Upgrading to version 4.5.2-beta2 is recommended to address this issue. Upgrading the affected component is advised. The vendor explains, that he was "[a]ble to reproduce in 6fcbf03 but not in 4.5.2-beta2".

CWE-476 Aug 24, 2025

CVE-2025-9019 3.1 LOW EPSS 0.00

A vulnerability has been found in tcpreplay 4.5.1. This vulnerability affects the function mask_cidr6 of the file cidr.c of the component tcpprep. The manipulation leads to heap-based buffer overflow. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The researcher is able to reproduce this with the latest official release 4.5.1 and the current master branch. The code maintainer cannot reproduce this for 4.5.2-beta1. In his reply the maintainer explains that "[i]n that case, this is a duplicate that was fixed in 4.5.2."
