Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU59290
Risk: High
CVSSv3.1: 8.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-21661
CWE-ID:
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data in WP_Query. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
MitigationUpdate wordpress package to one of the following versions: 5.0.15+dfsg1-0+deb10u1, 5.7.5+dfsg1-0+deb11u1.
Vulnerable software versionswordpress (Debian package): 5.0.1+dfsg1-1 - 5.7.3+dfsg1-0+deb11u1
CPE2.3http://www.debian.org/security/2022/dsa-5039
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
