Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU64730

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2019-0820

CWE-ID: CWE-400 - Uncontrolled Resource Consumption ('Resource Exhaustion')

Exploit availability: No

Description

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

The vulnerability exists when .NET Framework and .NET Core improperly process RegEx strings. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

Vulnerable software versions

IBM Robotic Process Automation: 21.0.0 - 21.0.2.4

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Information Exposure Through Timing Discrepancy

EUVDB-ID: #VU55035

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2020-15522

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a timing issue within the EC math library. A remote attacker who can observe timing information for the generation of multiple deterministic ECDSA signatures is able to reconstruct the private key used for encryption.

Mitigation

Install update from vendor's website.

3) Improper Verification of Cryptographic Signature

EUVDB-ID: #VU64732

Risk: High

CVSSv3.1:

CVE-ID: CVE-2021-43569

CWE-ID: CWE-347 - Improper Verification of Cryptographic Signature

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to verify function in the Stark Bank .NET ECDSA library (ecdsa-dotnet) fails to check that the signature is non-zero. A remote unauthenticated attacker can forge signatures on arbitrary messages to execute arbitrary code on the target system.

Mitigation

Install update from vendor's website.
