Grafana · Grafana · CVE-2023-4256
**Name of the Vulnerable Software and Affected Versions**
tcpreplay versions (affected versions not specified)
Grafana versions prior to 10.1.4
**Description**
A double free vulnerability has been identified in the `tcpedit dlt cleanup()` function within `plugins/dlt plugins.c` of tcpreplay's tcprewrite. This issue can be exploited by supplying a specifically crafted file to the tcprewrite binary, enabling a local attacker to initiate a Denial of Service (DoS) attack. Additionally, a directory traversal vulnerability in Grafana can lead to information disclosure.
**Recommendations**
For tcpreplay, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
For Grafana versions prior to 10.1.4, update to version 10.1.4 or later to resolve the directory traversal vulnerability.
