A buffer
overflow vulnerability exists in the embedded HTTP service in TL-WR841N v14 when processing
multipart/form-data requests. Insufficient validation of an attacker-controlled
boundary parameter may allow a remote unauthenticated attacker to submit a
crafted request that corrupts memory by overwriting data beyond the bounds of
an internal buffer.
Successful
exploitation may result in modification or corruption of process memory,
potentially leading to undefined application behavior. Arbitrary code
execution, information disclosure, and denial-of-service conditions have not
been demonstrated.
