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.
Details have emerged about a now-patched security vulnerability in Apple's iOS and macOS that, if successfully exploited, could sidestep the Transparency, Consent, and Control (TCC) framework and result in unauthorized access to sensitive information
Cybersecurity researchers have flagged a "critical" security vulnerability in Microsoft's multi-factor authentication (MFA) implementation that allows an attacker to trivially sidestep the protection and gain unauthorized access to a victim's account
Microsoft MFA flaw exposed that allowed attackers to bypass security within an hour, putting 400m Office 365 accounts at risk
Ivanti has released security updates to address multiple critical flaws in its Cloud Services Application (CSA) and Connect Secure products that could lead to privilege escalation and code execution
Embedded Device Operating Sytem Had Flaw Allowing Hacers to Bypass Integrity CheckA critical flaw in the updating service of a popular Linux operating system for embedded devices could enable hackers to compromise firmware with malicious images. OpenWrt developers patched the vulnerability, with a CVSS core of 9.3 and tracked as CVE-2024-54143.
