Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A **Remote Stack Buffer Overflow** in HP OpenView NNM. π **Consequences**: Triggered by a long HTTP GET request to `ovas.exe`, leading to **Arbitrary Code Execution** π₯.
Q2Root Cause? (CWE/Flaw)
π οΈ **Root Cause**: Flaw in `ovwparser.dll`. π **Flaw**: Fails to validate input length for `topology/homeBaseView` requests, causing a **Stack Overflow** π.
Q3Who is affected? (Versions/Components)
π’ **Affected**: HP OpenView Network Node Manager (OV NNM). π¦ **Component**: `ovas.exe` service running on **TCP Port 7510**. π **Published**: April 2008.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Hacker Power**: Execute **Arbitrary Commands** π₯οΈ. π **Impact**: Full control over the compromised system, potentially escalating privileges or stealing data π.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. π **Auth**: Likely **Unauthenticated** (Remote). βοΈ **Config**: Requires only network access to port 7510. No login needed to trigger the overflow! πͺ
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Public Exp?**: **YES**. π **Evidence**: References include OffSec PoC (`hp-nnm-ov.py.txt`) and X-Force/Secunia advisories. π **Wild Exp**: High risk due to public code availability.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **TCP Port 7510** open. π§ͺ **Test**: Send malformed HTTP GET requests to `ovas.exe`. π‘ **Tools**: Use Nmap or custom scripts to detect the service version.
Q8Is it fixed officially? (Patch/Mitigation)
π‘οΈ **Official Fix**: **YES**. π₯ **Action**: Apply HP Vendor Advisory **SSRT080033**. π **Update**: Patch `ovwparser.dll` or upgrade OV NNM to the fixed version.
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Mitigation**. π« **Block**: Firewall rules blocking **TCP 7510** from untrusted networks. π **Disable**: Stop `ovas.exe` service if not needed. π **Isolate**: Segment the network.
