Description
This security bulletin contains information about 1 vulnerability.
1) Argument injection attack (CVE-ID: CVE-2017-18266)
CWE-ID: CWE-88 - Argument Injection or Modification
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote unauthenticated attacker to conduct argument injection attack on the target system.
The weakness exists in the open_envvar function in the xdg-open component due to improper validation of user-supplied input. A remote attacker can trick the victim into following a specially crafted link that is designed to modify the BROWSER environment variable, conduct argument-injection attack, redirect the user's browser traffic to an attacker-controlled site and execute arbitrary commands.
