A security flaw has been disclosed in Kyocera’s Device Manager product that could be exploited by bad actors to carry out malicious activities on affected systems. "This vulnerability allows attackers to coerce authentication attempts to their own resources, such as a malicious SMB share, to capture or relay Active Directory hashed credentials if the ‘Restrict NTLM: Outgoing NTLM

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigations might apply in your situation: * Systems that have disabled NTLM are not affected. * Apply the existing group policy to block NTLM hash. With this policy enabled, this issue for a remote SMB location client or server can be mitigated. To enable the policy: Select **Computer Configuration** > **Windows Settings** > \*\* Security Settings\*\* > **Local Policies** > **Security Options**. On the right pane, double-click the Network security: Restrict NTLM: Outgoing NTLM traffic to remote servers policy per the options listed below in the Network security: **Restrict NTLM: Outgoing NTLM traffic to remote servers** documentation. **References**: * For customers running Windows Server 2008 or 2008 R2: Introducing the Restriction of NTLM Authentication * For customers runnin...

When an unpatched Windows 11 host loads a theme file referencing an msstyles file, Windows loads the msstyles file, and if that file's PACKME_VERSION is 999, it then attempts to load an accompanying dll file ending in _vrf.dll. Before loading that file, it verifies that the file is signed. It does this by opening the file for reading and verifying the signature before opening the file for execution. Because this action is performed in two discrete operations, it opens the procedure for a time of check to time of use vulnerability. By embedding a UNC file path to an SMB server we control, the SMB server can serve a legitimate, signed dll when queried for the read, but then serve a different file of the same name when the host intends to load/execute the dll.

sqlmap is an open source command-line automatic SQL injection tool. Its goal is to detect and take advantage of SQL injection vulnerabilities in web applications. Once it detects one or more SQL injections on the target host, the user can choose among a variety of options to perform an extensive back-end database management system fingerprint, retrieve DBMS session user and database, enumerate users, password hashes, privileges, databases, dump entire or user's specified DBMS tables/columns, run his own SQL statement, read or write either text or binary files on the file system, execute arbitrary commands on the operating system, establish an out-of-band stateful connection between the attacker box and the database server via Metasploit payload stager, database stored procedure buffer overflow exploitation or SMB relay attack and more.

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a new phishing campaign orchestrated by the Russia-linked APT28 group to deploy previously undocumented malware such as OCEANMAP, MASEPIE, and STEELHOOK to harvest sensitive information. The activity, which was detected by the agency between December 15 and 25, 2023, targets government entities

A researcher found two Microsoft vulnerabilities which could be combined to achieve zero-click remote code execution.

Technical details have emerged about two now-patched security flaws in Microsoft Windows that could be chained by threat actors to achieve remote code execution on the Outlook email service sans any user interaction. "An attacker on the internet can chain the vulnerabilities together to create a full, zero-click remote code execution (RCE) exploit against Outlook clients," Akamai security

Tutanota (Tuta Mail) is an encrypted email provider. Tutanota allows users to open links in emails in external applications. Prior to version 3.118.12, it correctly blocks the `file:` URL scheme, which can be used by malicious actors to gain code execution on a victims computer, however fails to check other harmful schemes such as `ftp:`, `smb:`, etc. which can also be used. Successful exploitation of this vulnerability will enable an attacker to gain code execution on a victim's computer. Version 3.118.2 contains a patch for this issue.

Improper input validation vulnerability in Newsletter Software SuperMailer affecting version 11.20.0.2204. An attacker could exploit this vulnerability by sending a malicious configuration file (file with SMB extension) to a user via a link or email attachment and persuade the user to open the file with the affected software on the local system. A successful exploit could allow the attacker to crash the application when attempting to load the malicious file.
