Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Information Exposure Through Timing Discrepancy

EUVDB-ID: #VU56790

Risk: Low

CVSSv4.0: 4.1 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-38153

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

the vulnerability exists due to some components in Apache Kafka use "Arrays.equals" to validate a password or key, which is vulnerable to timing attacks. A local user can abuse the "Arrays.equals" to brute force access credentials and escalate privileges on the system.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Spectrum Discover: 2.0.3 - 2.0.4.4

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Origin validation error

EUVDB-ID: #VU59319

Risk: Medium

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2021-3618

CWE-ID: CWE-346 - Origin Validation Error

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to a logic error in TLS implementation when handling different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A remote attacker with ability to perform TCP/IP layer MitM attack can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

This attack technique was dubbed ALPACA (application layer protocol content confusion attack).

Mitigation

Install update from vendor's website.
