Technical ContextAI · show details
This vulnerability is classified under CWE-121. A stack-based buffer overflow exists in the get_merge_mac function of the httpd binary on Linksys E1200 v2 routers (Firmware E1200_v2.0.11.001_us.tar.gz). The function concatenates up to six user-supplied CGI parameters matching <parameter>_0~5 into a fixed-size buffer (a2) without proper bounds checking, appending colon delimiters during concatenation. Remote attackers can exploit this vulnerability via specially crafted HTTP requests to execute arbitrary code or cause denial of service without authentication. Affected products include: Linksys E1200 Firmware.

How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
