Microsoft Entra User Lockout Multiple organizations reported widespread alerts and account lockouts this weekend from Microsoft Entra. The issue is caused by a new feature Microsoft enabled. This feature will lock accounts if Microsoft believes that the password for the account was compromised. https://www.bleepingcomputer.com/news/microsoft/widespread-microsoft-entra-lockouts-tied-to-new-security-feature-rollout/ https://learn.microsoft.com/en-us/entra/identity/authentication/feature-availability Erlang/OTP SSH Exploit An exploit was published for the Erlang/OTP SSH vulnerability. The vulnerability is easy to exploit, and the exploit and a Metasploit module allow for easy remote code execution. https://github.com/exa-offsec/ssh_erlangotp_rce/blob/main/ssh_erlangotp_rce.rb Sonicwall Exploited An older command injection vulnerability is now exploited on Sonicwall devices after initially gaining access by brute-forcing credentials. https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2021-0022 Unpatched Vulnerability in Bubble.io An unpatched vulnerability in the no-code platform bubble.io can be used to access any project hosted on the site. https://github.com/demon-i386/pop_n_bubble…

Online Services Again Abused to Exfiltrate Data Attackers like to abuse free online services that can be used to exfiltrate data. From the originals , like pastebin, to past favorites like anonfiles.com. The latest example is gofile.io. As a defender, it is important to track these services to detect exfiltration early https://isc.sans.edu/diary/Online%20Services%20Again%20Abused%20to%20Exfiltrate%20Data/31862 OpenSSH 10.0 Released OpenSSH 10.0 was released. This release adds quantum-safe ciphers and the separation of authentication services into a separate binary to reduce the authentication attack surface. https://www.openssh.com/releasenotes.html#10.0p1 Apache Roller Vulnerability Apache Roller addressed a vulnerability. Its CVSS score of 10.0 appears inflated, but it is still a vulnerability you probably want to address. https://lists.apache.org/thread/4j906k16v21kdx8hk87gl7663sw7lg7f CVE Funding Changes Mitre s government contract to operate the CVE system may run out tomorrow. This could lead to a temporary disruption of services, but the system is backed by a diverse board of directors representing many large companies. It is possible that non-government funding sources may keep the system afloat for now. https://www.cve.org/…
