Versions of the package djoser before 2.3.0 are vulnerable to Authentication Bypass when the authenticate() function fails. This is because the system falls back to querying the database directly, granting access to users with valid credentials, and eventually bypassing custom authentication checks such as two-factor authentication, LDAP validations, or requirements from configured AUTHENTICATION_BACKENDS.

Microsoft today released updates to plug at least 70 security holes in Windows and Windows software, including one vulnerability that is already being exploited in active attacks. The zero-day seeing exploitation involves CVE-2024-49138, a security weakness in the Windows Common… Read More »

December Microsoft Patch Tuesday. 89 CVEs, of which 18 were added since November MSPT. 1 vulnerability with signs of exploitation in the wild: 🔻 EoP – Windows Common Log File System Driver (CVE-2024-49138). There are no details about this vulnerability yet. Strictly speaking, there was another vulnerability that was exploited in the wild: EoP – […]

The zero-day (CVE-2024-49138), plus a worryingly critical unauthenticated RCE security vulnerability (CVE-2024-49112), are unwanted gifts for security admins this season.

The Patch Tuesday for December of 2024 includes 72 vulnerabilities, including four that Microsoft marked as “critical.” The remaining vulnerabilities listed are classified as “important.”

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**How could an attacker exploit this vulnerability?** An unauthenticated attacker who successfully exploited this vulnerability could gain code execution through a specially crafted set of LDAP calls to execute arbitrary code within the context of the LDAP service.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

The second zero-day vulnerability found in Windows NTLM in the past two months paves the way for relay attacks and credential theft. Microsoft has no patch, but released updated NTLM cyberattack mitigation advice.

Introduction In February 2024, we released an update to Exchange Server which contained a security improvement referenced by CVE-2024-21410 that enabled Extended Protection for Authentication (EPA) by default for new and existing installs of Exchange 2019. While we’re currently unaware of any active threat campaigns involving NTLM relaying attacks against Exchange, we have observed threat actors exploiting this vector in the past.
