#VU116213 Out-of-bounds write in OpenSSL - CVE-2025-9230
Vulnerability identifier: #VU116213
Vulnerability risk: High
CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]
CVE-ID:
CWE-ID:
CWE-787
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
OpenSSL
Server applications /
Encryption software
Vendor: OpenSSL Software Foundation
Description
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when trying to decrypt CMS messages encrypted using password based encryption. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.
Successful exploitation of the vulnerability requires that password based (PWRI) encryption support in CMS messages is enabled.
Mitigation
Install updates from vendor's website.
