Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack Buffer Overflow in Ultra Office Control. π **Consequences**: Remote attackers can execute arbitrary code via long parameters (strUrl, strFile, strPostData) sent via HTTP upload.β¦
π‘οΈ **Root Cause**: Stack-based buffer overflow. π **Flaw**: Improper handling of input length in the ActiveX control. β No bounds checking on the long string parameters allows memory corruption.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: Ultra Shareware Ultra Office Control. π¦ **Component**: OfficeCtrl.ocx. π’ **Version**: 2.0.2008.801. π **Context**: ActiveX control used in Visual C++/VB apps to display Office docs.
Q4What can hackers do? (Privileges/Data)
π» **Hackers' Power**: Execute arbitrary code. π **Privileges**: System-level access (depending on user context). π **Data**: Potential full data exfiltration or malware installation.β¦
π **Threshold**: LOW. π **Exploitation**: Remote & Unauthenticated. βοΈ **Config**: Triggered via HTTP upload parameters. π― No login or special config needed to trigger the overflow.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: YES. π **Evidence**: Exploit-DB ID 6318 listed. π **Wild Exploitation**: References to Shinnai.net and SecurityFocus BID 30861 indicate public knowledge and potential active exploitation.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for OfficeCtrl.ocx. π **Version Check**: Verify if version is 2.0.2008.801. πΈοΈ **Network**: Monitor for HTTP uploads with unusually long strUrl/strFile/strPostData parameters.β¦
π οΈ **Official Fix**: Data does not list a specific vendor patch link. β οΈ **Status**: Published 2008-09-02. π **Implication**: Likely obsolete or requires vendor-specific legacy support.β¦
π§ **Workaround**: Disable or remove Ultra Office Control. π« **Block**: Restrict HTTP uploads with long parameters via WAF. π‘οΈ **Isolate**: Sandboxed environments for legacy apps.β¦
π₯ **Urgency**: HIGH (Historically). β³ **Priority**: Immediate remediation if still in use. π **Age**: Vulnerability is from 2008. π¨ **Risk**: Critical impact (RCE) with low barrier to entry.β¦
