Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Remote Code Execution (RCE) in IE's TDC ActiveX control. π₯ **Consequences**: Attackers trigger memory corruption via long URLs, allowing arbitrary code execution on the victim's machine.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Buffer overflow/Memory corruption. Specifically, the `CTDCCtl::SecurityCHeckDataURL` function fails to handle excessively long `DataURL` parameters correctly.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: Microsoft Internet Explorer 5.01 SP4 and IE6. π₯οΈ **OS**: Windows XP SP2, SP3, and Windows Server 2003 SP1.
Q4What can hackers do? (Privileges/Data)
π» **Hackers' Power**: Full arbitrary code execution. This typically grants the attacker **system-level privileges** or the same rights as the current user, potentially leading to total system compromise.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. It is a remote vulnerability. No authentication is needed. Victims just need to visit a malicious webpage containing the crafted URL.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: Yes. References include ZDI-10-034 and SecurityFocus archives. While specific PoC code isn't in the snippet, the advisory confirms active exploitation awareness and public disclosure.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for IE versions 5.01 SP4 or 6 on Windows XP/2003. Look for the presence of the Tabular Data Control (TDC) ActiveX component in browser configurations.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fixed?**: Yes. Microsoft released **MS10-018** to patch this vulnerability. Users should apply this security update immediately.
Q9What if no patch? (Workaround)
π§ **No Patch?**: Disable ActiveX controls or restrict Internet Explorer to 'Restricted Sites'. Use a modern, non-vulnerable browser if possible. Avoid clicking unknown links.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. As an RCE vulnerability in a widely used browser on older OSs, it allows remote takeover. Immediate patching (MS10-018) is essential.
