This year at the Nullcon International Security Conference I shared practical advice for how security researchers can maximize the impact of their security vulnerability submissions and earn higher bounty awards under the Microsoft Bounty Program. For those who couldn’t be there, I had two core pieces of advice. First , focus vulnerability research on the products and services that are eligible for bounty rewards.

### Impact All users on Windows are impacted. MinIO fails to filter the `\` character, which allows for arbitrary object placement across buckets. As a result, a user with low privileges, such as an access key, service account, or STS credential, which only has permission to `PutObject` in a specific bucket, can create an admin user. ### Patches There are two patches that fix this problem comprehensively ``` commit b3c54ec81e0a06392abfb3a1ffcdc80c6fbf6ebc Author: Harshavardhana <[email protected]> Date: Mon Mar 20 13:16:00 2023 -0700 reject object names with '\' on windows (#16856) ``` ``` commit 8d6558b23649f613414c8527b58973fbdfa4d1b8 Author: Harshavardhana <[email protected]> Date: Mon Mar 20 00:35:25 2023 -0700 fix: convert '\' to '/' on windows (#16852) ``` ### Workarounds There are no known workarounds ### References The vulnerable code: ```go // minio/cmd/generic-handlers.go // Check if the incoming path has bad path components, // such as ".." and "." // SlashSep...

An issue was discovered in Veritas Backup Exec before 21.2. It supports multiple authentication schemes: SHA authentication is one of these. This authentication scheme is no longer used in current versions of the product, but hadn't yet been disabled. An attacker could remotely exploit this scheme to gain unauthorized access to an Agent and execute privileged commands.

An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to gain unauthorized access and complete the authentication process. Subsequently, the client can execute data management protocol commands on the authenticated connection. By using crafted input parameters in one of these commands, an attacker can access an arbitrary file on the system using System privileges.
