Buffer Overflow in HP Tru64 UNIX /usr/bin/at

IdentifiersCVE-2002-1614CWE-120

A buffer overflow vulnerability exists in HP Tru64 UNIX in the /usr/bin/at utility. Local users can exploit this vulnerability by providing a long argument to the at command, causing a buffer overflow and potentially allowing the execution of arbitrary code with elevated privileges.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows local attackers to execute arbitrary code, likely with the privileges of the at utility, which may be setuid root, leading to full system compromise.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to /usr/bin/at to trusted users only, and monitor for unusual usage. Employ system-level protections such as stack canaries, non-executable stacks, or address space layout randomization (ASLR) if available on the platform.

Remediation

Patch, then assume compromise.

Apply the vendor-supplied patches or updates that address this buffer overflow vulnerability. If patches are not available, consider disabling or restricting access to the /usr/bin/at utility.

CVE-2002-1614MaturityPoCVerified exploit

This repository contains a local privilege escalation exploit targeting CVE-2002-1614, a vulnerability in the /usr/bin/at binary on Tru64 UNIX 4.0g systems. The main file, exploit.c, is a proof-of-concept C program that constructs a buffer overflow payload, sets an environment variable (ATEX), and executes /usr/bin/at with a crafted argument to trigger the vulnerability. The embedded shellcode is Alpha architecture assembly that sets the user ID to 0 (root) and spawns a shell (/bin/sh). The exploit requires local access to the target system, executable stack enabled, and is intended for educational or authorized penetration testing use. The repository also includes a README with compilation and usage instructions, and a standard MIT license. No network endpoints are present; all actions are performed locally on the target system.
