Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: iSeeQ Hybrid DVR WH-H4 has a critical flaw in `get_jpeg` script. <br>β οΈ **Consequences**: Attackers can bypass access controls to steal **real-time video streams**.β¦
π‘οΈ **Root Cause**: **CWE-306** (Missing Authentication for Critical Function). <br>β **Flaw**: The `get_jpeg` endpoint lacks proper **unauthenticated access validation**. It trusts requests blindly.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: iSeeQ (South Korea). <br>π¦ **Product**: Hybrid DVR WH-H4. <br>π’ **Affected Version**: Specifically **1.03R**. Check your firmware version immediately!
Q4What can hackers do? (Privileges/Data)
π» **Privileges**: **None required**. No login needed. <br>πΉ **Data Access**: Full access to **live video feeds**. Hackers can watch what the camera sees in real-time.β¦
π **Threshold**: **Extremely Low**. <br>π **Auth**: **No authentication** required. <br>π **Network**: Remote exploitation possible (AV:N). <br>π― **Complexity**: Low (AC:L). Anyone with network access can exploit it.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Public Exploit**: **YES**. <br>π **ExploitDB**: ID **47562**. <br>π **Advisory**: Zero Science Lab (ZSL-2019-5539). <br>β οΈ **Status**: Wild exploitation is possible. PoCs are available online.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for the **`get_jpeg`** endpoint. <br>π§ͺ **Test**: Send a request without credentials. If you get a JPEG stream, you are vulnerable.β¦
π§ **No Patch Workaround**: <br>1. π« **Block Access**: Firewall rules to block external access to the DVR's web port. <br>2. π **Network Segmentation**: Isolate DVRs on a private VLAN. <br>3.β¦
π₯ **Urgency**: **CRITICAL (P1)**. <br>β‘ **Priority**: Fix immediately. <br>π **Risk**: CVSS **9.1** (High). <br>ποΈ **Impact**: Real-time video theft is a severe privacy breach. Do not ignore this!
