Exploitability
| CWE ID | Description |
|---|---|
| CWE-119 | The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. |
| CWE-121 | A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a stack-based buffer overflow in the TOTOLINK A3300R router's setScheduleCfg function within the /cgi-bin/cstecgi.cgi file. It occurs due to improper handling of the recHour parameter in the POST request, allowing an attacker to remotely exploit this flaw by sending specially crafted input to overflow the buffer. [1]
How can this vulnerability impact me? :
Exploitation of this vulnerability can lead to severe impacts including remote code execution, denial of service, or unauthorized control over the affected device. Since the attack can be initiated remotely without user interaction, it poses a high risk to the security and availability of the device and potentially the network it is connected to. [1]
