CVE-2021-43298

CVE-2021-43298

The code that performs password matching when using ‘Basic’ HTTP authentication does not use a constant-time memcmp and has no rate-limiting. This means that an unauthenticated network attacker can brute-force the HTTP basic password, byte-by-byte, by recording the webserver’s response time until the unauthorized (401) response.

CVE-2021-41598

A UI misrepresentation vulnerability was identified in GitHub Enterprise Server that allowed more permissions to be granted during a GitHub App’s user-authorization web flow than was displayed to the user during approval. To exploit this vulnerability, an attacker would need to create a GitHub App on the instance and have a user authorize the application through the web authentication flow. All permissions being granted would properly be shown during the first authorization, but if the user later updated the set of repositories the app was installed on after the GitHub App had configured additional user-level permissions, those additional permissions would not be displayed, leading to more permissions being granted than the user potentially intended. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.3 and was fixed in versions 3.2.5, 3.1.13, 3.0.21. This vulnerability was reported via the GitHub Bug Bounty program.

CVE-2021-34867

CVE-2021-34867

This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Desktop 16.1.3-49160. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the Toolgate component. The issue results from the lack of proper validation of user-supplied data, which can result in an uncontrolled memory allocation. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-13672.
