CVE-2026-30603 Details
Description
An issue in the firmware update mechanism of Qianniao QN-L23PA0904 v20250721.1640 allows attackers to gain root access, install backdoors, and exfiltrate data via supplying a crafted iu.sh script contained in an SD card.
A vulnerability in the Qianniao QN-L23PA0904 IP security camera's firmware update process allows for arbitrary root code execution. This issue arises because the camera executes a user-supplied shell script from an SD card during boot, without any integrity or authenticity checks. By placing a crafted 'iu.sh' script in an 'upgrade' directory on the SD card, attackers can gain root access, install backdoors, and exfiltrate data.
