1) Out-of-bounds read

EUVDB-ID: #VU63945

Risk: Medium

CVSSv4.0: 6.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service attack.

The vulnerability exists due to a boundary condition in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds read error, gain access to sensitive information or perform a denial of service attack.

2) SQL injection

EUVDB-ID: #VU63343

Risk: High

CVSSv4.0: 8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2022-29155

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data in the experimental back-sql backend to slapd during an LDAP search operation when the search filter is processed. 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.

Mitigation

Install update from vendor's website.
