Loading vulnerability…
A vulnerability in Termius prior to version 9.9.0 allows a local attacker to execute arbitrary code by leveraging the DYLD_INSERT_LIBRARIES environment variable. By supplying a crafted script, an attacker can inject a malicious dynamic library into the Termius process, leading to arbitrary code execution.

This repository provides a proof-of-concept (POC) exploit for CVE-2024-55503, a local code injection vulnerability in the Termius App for macOS (versions before 9.9.0). The exploit leverages the DYLD_INSERT_LIBRARIES environment variable to inject a malicious dynamic library into the Termius process. The main exploit code (main8.m) is an Objective-C file that, when compiled as a dylib and loaded into Termius, executes a shell command to read the first 20 lines of /etc/passwd, demonstrating arbitrary code execution. The repository consists of a README.md explaining the vulnerability, usage instructions, and a reference to the CVE, and a single code file (main8.m) containing the exploit logic. The attack vector is local, requiring the attacker to execute Termius with a crafted environment. The endpoints identified include the target application binary and the /etc/passwd file accessed by the payload.
