Vulnerability Details
CVEID: CVE-2020-15522
DESCRIPTION: Bouncy Castle BC Java, BC C# .NET, BC-FJA, BC-FNA could allow a remote attacker to obtain sensitive information, caused by a timing issue within the EC math library. By utilize cryptographic attack techniques, an attacker could exploit this vulnerability to obtain the private key information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/202188 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2021-43569
DESCRIPTION: Stark Bank Elixir .NET ECDSA library (ecdsa-dotnet) could allow a remote attacker to bypass security restrictions, caused by the failure to check that the signature is non-zero. By sending a specially-crafted request, an attacker could exploit this vulnerability to authenticate as any user within the Stark Bank platform, and bypass signature verification needed to perform operations on the platform.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/213249 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2019-0820
DESCRIPTION: Microsoft .NET Framework and .NET Core is vulnerable to a denial of service, caused by improper processing of RegEx strings. By sending a specially-crafted request, an attacker could exploit this vulnerability to cause a denial of service condition in .NET application.
CVSS Base score: 5.3
