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.
Hackers are launching attacks against Palo Alto Networks PAN-OS firewalls by exploiting a recently fixed vulnerability (CVE-2025-0108) that allows bypassing authentication. [...]
Attackers are now targeting an authentication bypass vulnerability affecting SonicWall firewalls shortly after the release of proof-of-concept (PoC) exploit code. [...]
