Background for this topic.
Bypass describes attacker methods that circumvent specific security controls, such as authentication checks, input validation, or detection systems, without directly exploiting the underlying vulnerability. These techniques often leverage design flaws, misconfigurations, or protocol weaknesses to evade protections like firewalls, multi-factor authentication, or antivirus scanning.
Bypassing controls can enable unauthorized access, data exfiltration, or persistent presence while avoiding alerts, complicating detection and response. Effective defense requires layered security measures, rigorous configuration management, and continuous validation of control effectiveness to identify and close bypass paths before attackers exploit them.
Today, Ivanti warned of a new authentication bypass vulnerability impacting Connect Secure, Policy Secure, and ZTA gateways, urging admins to secure their appliances immediately. [...]
JetBrains urged customers today to patch their TeamCity On-Premises servers against a critical authentication bypass vulnerability that can let attackers take over vulnerable instances with admin privileges. [...]
