Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Cryptographic issues

EUVDB-ID: #VU21043

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-1547

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to decrypt traffic.

The vulnerability exists due to insufficient enforcement of side channel resistant code paths. A remote attacker with ability to create a large number of signatures, where explicit parameters with no co-factor is present, can force the application to fall back to non-side channel resistant code pathsduring ECDSA signature operation and perform full key recovery.

Successful exploitation of the vulnerability may allow an attacker to decrypt communication between server and client.

Mitigation

Install update from vendor's website.

2) Cross-site scripting

EUVDB-ID: #VU20384

Risk: Low

CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-10092

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 on the mod_proxy error page. A remote attacker can trick the victim to follow a specially crafted link 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 update from vendor's website.
