List of CVEs: CVE-2021-36260
This module exploits an unauthenticated command injection in
a variety of Hikvision IP cameras (CVE-2021-36260). The
module inserts a command into an XML payload used with an
HTTP PUT request sent to the /SDK/webLanguage endpoint,
resulting in command execution as the root user. This
module specifically attempts to exploit the blind variant of
the attack. The module was successfully tested against an
HWI-B120-D/W using firmware V5.5.101 build 200408. It was
also tested against an unaffected DS-2CD2142FWD-I using
firmware V5.5.0 build 170725. Please see the Hikvision
advisory for a full list of affected products.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Description
This module exploits an unauthenticated command injection in a variety of Hikvision IP
cameras (CVE-2021-36260). The module inserts a command into an XML payload used with an
HTTP PUT request sent to the /SDK/webLanguage endpoint, resulting in command execution
as the root user.
This module specifically attempts to exploit the blind variant of the attack. The module was successfully tested against an HWI-B120-D/W using firmware V5.5.101 build 200408. It was also tested against an unaffected DS-2CD2142FWD-I using firmware V5.5.0 build 170725. Please see the Hikvision advisory for a full list of affected products.
The injection space is very small. The entire snprintf is 0x1f bytes and the format string is:
/dav/%s.tar.gz
Which accounts for 12 bytes, leaving only 19 bytes for our payload. Fortunately, snprintf will let us reclaim '.tar.gz' so in reality, there are 26 bytes for our payload. We need 3 bytes to invoke our injection: $(). Leaving 23 bytes for payload. The 'echo' stager has a minimum of 26 bytes but we obviously don't have that much space. We can steal the extra space from the "random" file name and compress ' >> ' to '>>'. That will get us below 23. Squeezing the extra bytes will also allow printf stager to do more than 1 byte per exploitation.
Installation
Hikvision cameras are physical devices and aren't known to have been successfully emulated. Actually, they are fairly well known for having encrypted firmware. Either way, if you have a device, you can determine if you have an affected device/firmware by referencing the table in the Hikvision advisory.
Verification Steps
- Acquire an affected device
- Do:
use exploit/linux/http/hikvision_cve_2021_36260_blind - Do:
set RHOST <ip> - Do:
check - Verify the remote target is flagged as vulnerable
- Do:
set LHOST <ip> - Do:
exploit - You should get a bind shell.
Options
Target 0
Target 0 is a busybox telnetd bind shell.
Target 1
Target 1 is a the reverse tcp meterpreter stager. Because the payload space is so small it takes quite a few requests to upload the stager and execute it (100+).
Scenarios
Hikvision HWI-B120-D/W using firmware V5.5.101 build 200408. Root shell via bind shell.

Payload information:
Description:
This module exploits an unauthenticated command injection in a
variety of Hikvision IP cameras (CVE-2021-36260). The module inserts
a command into an XML payload used with an HTTP PUT request sent to
the `/SDK/webLanguage` endpoint, resulting in command execution as
the `root` user. This module specifically attempts to exploit the
blind variant of the attack. The module was successfully tested
against an HWI-B120-D/W using firmware V5.5.101 build 200408. It was
also tested against an unaffected DS-2CD2142FWD-I using firmware
V5.5.0 build 170725. Please see the Hikvision advisory for a full
list of affected products.
