No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

4) Comparison using wrong factors

EUVDB-ID: #VU49086

Risk: High

CVSSv3.1: 7.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2020-28052

CWE-ID: CWE-1025 - Comparison using wrong factors

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to brute-force password hashes.

The vulnerability exists due to comparison error in OpenBSDBCrypt.checkPassword() function in core/src/main/java/org/bouncycastle/crypto/generators/OpenBSDBCrypt.java when matching passwords with hashes. A remote attacker can pass an incorrect password that will be accepted as a valid one by the library, bypass authentication process and gain unauthorized access to the application that uses vulnerable version of Bouncy Castle.

Mitigation

Install update from vendor's website.

5) Resource exhaustion

EUVDB-ID: #VU27513

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-11612

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to application does not properly control consumption of internal resources within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

Mitigation

Install update from vendor's website.
