Exploitation Summary

EIP tracks 1 public exploit for CVE-2020-28054. PoCs published by VoidSec.

AI-analyzed exploit summary This repository contains a proof-of-concept exploit for a stack-based buffer overflow in IBM Tivoli Storage Manager's ITSM Administrator Client (dsmadmc.exe) version 5.2.0.1. The exploit leverages a vulnerable 'id' field to execute arbitrary shellcode, achieving remote code execution (RCE) on Windows systems.

Description

JamoDat TSMManager Collector version up to 6.5.0.21 is vulnerable to an Authorization Bypass because the Collector component is not properly validating an authenticated session with the Viewer. If the Viewer has been modified (binary patched) and the Bypass Login functionality is being used, an attacker can request every Collector's functionality as if they were a properly logged-in user: administrating connected instances, reviewing logs, editing configurations, accessing the instances' consoles, accessing hardware configurations, etc.Exploiting this vulnerability won't grant an attacker access nor control on remote ISP servers as no credentials is sent with the request.
