Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack buffer overflow in `ERM_convert_to_correct_webpath()` function within `ermapper_u.dll`.β¦
π‘οΈ **Root Cause**: **Stack-based buffer overflow**. <br>π **Flaw**: The function fails to properly validate the length of path names provided in ERS files before copying them to the stack.β¦
π¦ **Affected Product**: **ERDAS ER Viewer** by Intergraph. <br>π **Version**: Versions **prior to 13.00.0001**. <br>π§ **Component**: Specifically the `ermapper_u.dll` library.
Q4What can hackers do? (Privileges/Data)
π» **Hackers' Power**: Execute **arbitrary code** remotely. <br>π **Privileges**: Likely runs with the privileges of the user opening the malicious ERS file.β¦
β οΈ **Threshold**: **Low**. <br>π **Auth**: No authentication required. <br>βοΈ **Config**: Exploitation relies on the victim opening a crafted **ERS file**. Social engineering or file sharing is the primary vector.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: The provided data lists **no specific PoC code** in the `pocs` array.β¦
π§ **No Patch Workaround**: <br>1οΈβ£ **Disable** ERDAS ER Viewer if not needed. <br>2οΈβ£ **Do not open** ERS files from untrusted sources. <br>3οΈβ£ **Sandboxes**: Run the viewer in a restricted environment or VM.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **High**. <br>β³ **Priority**: Immediate patching recommended. <br>π **Risk**: Remote code execution via file opening is a high-impact, low-effort attack vector for attackers.
