Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: BigAnt IM Server (AntServer.exe) has a **Stack Buffer Overflow** in HTTP GET request handling.β¦
π‘οΈ **Root Cause**: Improper bounds checking on HTTP GET parameters. The `AntServer` module fails to validate input length, causing a **Stack Overflow** when processing excessively long strings via TCP port 6660.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **BigAnt Messenger** (Enterprise IM Platform). Specifically the **AntServer.exe** component. Note: Vendor listed as 'n/a' in data, but product is clearly BigAnt.
Q4What can hackers do? (Privileges/Data)
π **Attacker Impact**: Full **Remote Code Execution (RCE)**. Hackers can execute arbitrary commands with the privileges of the **AntServer process**. This likely means **System/Admin level control** over the server.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Exploitation Threshold**: **LOW**. No authentication required. Attackers just need network access to **TCP port 6660**. A single crafted HTTP GET packet is sufficient to trigger the exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exploit**: **YES**. Exploit-DB IDs **9690** and **9673** are available. GitHub PoC exists (`war4uthor/CVE-2009-4660`). Tested on **Windows XP SP3**. Wild exploitation is highly probable.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **BigAnt Messenger** services listening on **TCP port 6660**. Look for `AntServer.exe` processes. Use network scanners to detect the specific IM protocol signature if available.
π§ **Workaround**: **Block TCP Port 6660** at the firewall. Restrict access to the BigAnt server interface. Disable the service if not strictly needed. Isolate the server from untrusted networks.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. Since it allows **RCE** with **no auth** and has **public exploits**, this is a critical risk. Immediate mitigation (firewall rules) is required if the service is exposed to the internet.
