Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: HP Data Protector's `dpwinsup.dll` has a **memory leak** flaw. <br>π₯ **Consequences**: Sending a crafted packet causes the `dpwingad` process (on TCP/3817) to **crash**.β¦
π‘οΈ **Root Cause**: The vulnerability lies in the **`dpwinsup.dll` module**. It fails to handle specific crafted packets from remote clients correctly, resulting in **memory leakage** and instability.β¦
π’ **Affected**: **HP Data Protector** software. Specifically, the backup domain server component running the `dpwinsup.dll` module. Supports disk/tape backup via private protocols.
Q4What can hackers do? (Privileges/Data)
π΅οΈ **Attacker Impact**: Hackers can cause **Denial of Service (DoS)** by crashing the process. They can also potentially **leak arbitrary memory contents**, which might expose sensitive backup data or system info.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Low**. Requires sending a **crafted packet** to the remote client communication channel. No authentication mentioned; relies on network access to TCP/3817.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exploits**: **YES**. Exploit-DB lists exploits **#9006** and **#9007**. Secunia (35084) and Vupen (ADV-2009-1309) also have advisories. Active exploitation resources exist.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **HP Data Protector** services. Check if **TCP port 3817** is open and listening. Verify if the `dpwinsup.dll` module is present and unpatched on the backup domain server.
π§ **No Patch Workaround**: **Block TCP port 3817** at the firewall. Restrict access to the private protocol communication. Restart the `dpwingad` process if it crashes to restore service temporarily.
Q10Is it urgent? (Priority Suggestion)
β οΈ **Urgency**: **HIGH**. Public exploits exist. It causes **DoS** and **Memory Leak**. Since it affects critical backup infrastructure, immediate mitigation (firewall rules) is recommended until a patch is applied.
