| विवरण | BL-AC3600
Version 1.0.22
The password modification function lacks content filtering, resulting in a command injection vulnerability.
Technical Analysis:
● v8 is a pointer to the routepwd field
● v9 represents the user-input value
● The strcpy function copies the value of v9 to v37
● easy_uci_set_option_string_0 concatenates "chpasswd.sh root" with v37 and passes it to v36
● The concatenated string is directly executed by the system function
●
Proof of Concept:
1. Craft malicious request packet
2. Observe "Operation Successful" response
3. Successfully establish reverse shell
Vulnerability Validation:
Command injection confirmed through reverse shell acquisition.
