CVE-2017-18266
CVSS v2.0

Alta
| Vetor | AV:N/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions:
xdg-utils versions prior to 1.1.3
Description:
The issue is related to the
open envvar function in xdg-open, which does not properly validate strings before launching the program specified by the BROWSER environment variable. This could allow remote attackers to conduct argument-injection attacks via a crafted URL. For example, using %s in the BROWSER environment variable could lead to such an attack. The vulnerability might also allow a remote attacker to gain unauthorized access to information and disrupt its integrity and availability.Recommendations:
For versions prior to 1.1.3, update to version 1.1.3 or later to resolve the issue. As a temporary workaround, consider validating the strings passed to the
open envvar function or restricting the use of the BROWSER environment variable to minimize the risk of exploitation.Correção
