Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Use of Uninitialized Variable

EUVDB-ID: #VU98022

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-9355

CWE-ID: CWE-457 - Use of Uninitialized Variable

Exploit availability: No

Description

The vulnerability allows a remote attacker to weaken TLS encryption.

The vulnerability exists due to an uninitialized buffer length variable in the CGO bindings that intermittently return a zeroed buffer from (*boringHMAC).Sum() in FIPS mode. A remote attacker can randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode and weaken TLS security.

Mitigation

Install updates from vendor's website.

2) DOM-based cross-site scripting

EUVDB-ID: #VU99261

Risk: Medium

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-47875

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can pass specially crafted input to the application and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

Install updates from vendor's website.
