Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Remote Command Injection in D-Link DSL-2750B. ๐ฅ **Consequences**: Attackers can execute arbitrary OS commands via the `login.cgi-cli` parameter. Total device compromise is possible.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: Improper input validation in the `login.cgi` script. ๐ **Flaw**: The `cli` parameter is not sanitized, allowing shell metacharacters to be injected directly into system commands.
Q3Who is affected? (Versions/Components)
๐ฆ **Affected**: D-Link DSL-2750B Wireless Router. ๐ **Version**: Firmware versions **prior to 1.05**. Newer versions are safe.
Q4What can hackers do? (Privileges/Data)
๐ **Privileges**: Unauthenticated Remote Code Execution (RCE). ๐ **Data**: Full control over the router. Hackers can read configs, steal credentials, or pivot to your internal network.
Q5Is exploitation threshold high? (Auth/Config)
โก **Threshold**: **LOW**. ๐ **Auth**: **None required**. The vulnerability is **unauthenticated**. Anyone on the network (or internet if exposed) can exploit it.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Exploit**: **YES**. Public PoC exists on Exploit-DB (ID: 44760) and Full Disclosure. ๐ **Wild Exploitation**: High risk due to ease of use and lack of auth.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for D-Link DSL-2750B devices. ๐งช **Test**: Send crafted requests to `/login.cgi-cli` with shell commands. Look for unexpected command output in the response.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Fix**: **YES**. Official patch released by D-Link. ๐ฅ **Action**: Upgrade firmware to **version 1.05 or later**. Check D-Link support announcements (SAP10088).
Q9What if no patch? (Workaround)
๐ง **Workaround**: If patching is delayed, **block external access** to the router's management interface. ๐ Disable remote management features immediately.
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **CRITICAL**. ๐จ **Priority**: Patch immediately. Unauthenticated RCE is a top-tier threat. Do not leave vulnerable routers exposed to the internet.
