Security Bulletin
This security bulletin contains one high risk vulnerability.
EUVDB-ID: #VU19947
Risk: High
CVSSv4.0: 7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]
CVE-ID: CVE-2019-14744
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when processing .desktop
and .directory
files within the KConfigGroup::readEntry() function. A remote attacker can create a specially crafted file or folder, trick the user into opening it and execute arbitrary OS commands with privileges of the current user.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Examples: 1) payload.desktop [Desktop Entry] Icon[$e]=$(echo${IFS}0>~/Desktop/zero.lol&) 2) .directory [Desktop Entry] Type=Directory Icon[$e]=$(echo${IFS}0>~/Desktop/zero.lol&)Mitigation
