Security researchers have disclosed multiple architectural vulnerabilities in Siemens SIMATIC and SIPLUS S7-1500 programmable logic controllers (PLCs) that could be exploited by a malicious actor to stealthily install firmware on affected devices and take control of them. Discovered by Red Balloon Security, the issues are tracked as CVE-2022-38773 (CVSS score: 4.6), with the low severity

An issue has been discovered in GitLab CE/EE affecting all versions before 15.5.7, all versions starting from 15.6 before 15.6.4, all versions starting from 15.7 before 15.7.2. A race condition can lead to verified email forgery and takeover of third-party accounts when using GitLab as an OAuth provider.

This Tech Tip outlines the steps enterprise defenders should take as they protect their data in cloud environments in response to the security incident with the CI/CD platform.

ZITADEL is a combination of Auth0 and Keycloak. RefreshTokens is an OAuth 2.0 feature that allows applications to retrieve new access tokens and refresh the user's session without the need for interacting with a UI. RefreshTokens were not invalidated when a user was locked or deactivated. The deactivated or locked user was able to obtain a valid access token only through a refresh token grant. When the locked or deactivated user’s session was already terminated (“logged out”) then it was not possible to create a new session. Renewal of access token through a refresh token grant is limited to the configured amount of time (RefreshTokenExpiration). As a workaround, ensure the RefreshTokenExpiration in the OIDC settings of your instance is set according to your security requirements. This issue has been patched in versions 2.17.3 and 2.16.4.

More than 120 models of Siemens' S7-1500 PLCs contain a serious vulnerability—and no fix is on the way.

An incorrect authorization vulnerability was identified in GitHub Enterprise Server that allowed a repository-scoped token with read/write access to modify Action Workflow files without a Workflow scope. The Create or Update file contents API should enforce workflow scope. This vulnerability affected all versions of GitHub Enterprise Server prior to version 3.7 and was fixed in versions 3.3.16, 3.4.11, 3.5.8, and 3.6.4. This vulnerability was reported via the GitHub Bug Bounty program.
