VULNERABLE PRODUCT ------------------ Software: KillProcess Platforms: Windows Version: 2.20 and priors Original advisorie: http://sbox.nightmail.ru -------------------------- BACKGROUND ---------- This funny application can terminate any Windows process with the click of a button. It can also prevent unwanted processes from ever executing by scanning the active process list for unwanted processes and terminating them on sight. Source: http://orangelampsoftware.com DESCRIPTION ------------- A malicious .exe file with a long FileDescription in version resource can generate a local exploitation of a buffer overflow and allows attackers to execute arbitrary code. PROOF OF CONCEPT ---------------- I've code a 2,78 Ko PoC. FileDescription have been set to A x 544 bytes. PoC is available here: http://sbox.nightmail.ru/KillProc_PoC.exe There is another little bug, but not really dangerous. If you add an application to killlist, then lunch it. Ok, boom ... But if you start XX same process at the same time, all applications will not be killed. ANALYSIS -------- Exploitation of the described vulnerability allows attackers to execute arbitrary code under the context of the user who started KillProcess. VENDOR STATUS ------------- Vendor have been contacted. Thanks ------ Greet's fly out to ATmaCA. This idea was first credit by Kozan.
