Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack-based buffer overflow in `rf_report_error()` function within `ermapper_u.dll`.β¦
π‘οΈ **Root Cause**: Improper bounds checking in the `rf_report_error` function. It fails to validate input length, leading to a **Stack-Based Buffer Overflow** when processing malicious ERS files.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: Intergraph ERDAS ER Viewer. Specifically, versions **prior to 13.0.1.1301**. The vulnerable component is the `ermapper_u.dll` file.
Q4What can hackers do? (Privileges/Data)
π» **Attacker Capabilities**: Full **Remote Code Execution (RCE)** or **DoS**. By crafting a malicious ERS file, an attacker can hijack the process context, potentially gaining system-level privileges.
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Low**. No authentication required. The attack vector is delivering a malicious ERS file (e.g., via email or shared drive). The user simply needs to open/view the file.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exploit**: **Yes**. Exploit-DB ID **26708** is available. Secunia and OSVDB also reference active exploitation vectors. Wild exploitation is possible.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `ermapper_u.dll` version numbers. Check installed software for **ERDAS ER Viewer < 13.0.1.1301**. Look for ERS file handling in network traffic or user activity logs.
π§ **No Patch Workaround**: **Disable** the ER Viewer application. Do not open ERS files from untrusted sources. Use alternative, secure image viewers that do not rely on the vulnerable DLL.
Q10Is it urgent? (Priority Suggestion)
β οΈ **Urgency**: **HIGH**. It is a remote, unauthenticated RCE vulnerability with public exploits. Immediate patching or isolation is critical to prevent system compromise.
