Improper Authentication

An improper authentication vulnerability leading to information leakage was discovered in iptime NAS2dual. Remote attackers are able to steal important information in the server by exploiting vulnerabilities such as insufficient authentication when accessing the shared folder and changing user’s passwords.Show less

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system.Show less

A lack of password change protection vulnerability in a depreciated API of McAfee Enterprise ePolicy Orchestrator (ePO) prior to 5.10 Update 13 allows a remote attacker to change the password of a compromised session without knowing the existing user's password. This functionality was removed from the User Interface in ePO 10 and the API has now been disabled. Other protection is in place to reduce the likelihood of this being successful through sending a link to a logged in user.Show less

An access control issue in the authentication module of Lexar_F35 v1.0.34 allows attackers to access sensitive data and cause a Denial of Service (DoS). An attacker without access to securely protected data on a secure USB flash drive can bypass user authentication without having any information related to the password of the registered user. The secure USB flash drive transmits the password entered by the user to the authentication module in the drive after the user registers a password, and then the input password is compared with the registered password stored in the authentication module. Subsequently, the module returns the comparison result for the authentication decision. Therefore, an attacker can bypass password authentication by analyzing the functions that return the password verification or comparison results and manipulate the authentication result values. Accordingly, even if attackers enter an incorrect password, they can be authenticated as a legitimate user and can therefore exploit functions of the secure USB flash drive by manipulating the authentication result values.Show less

An authentication issue was addressed with improved state management. This issue is fixed in macOS Big Sur 11.6.5, macOS Monterey 12.3, Security Update 2022-003 Catalina. A local attacker may be able to view the previous logged in user’s desktop from the fast user switching screen.Show less

OpenVPN 2.1 until v2.4.12 and v2.5.6 may enable authentication bypass in external authentication plug-ins when more than one of them makes use of deferred authentication replies, which allows an external user to be granted access with only partially correct credentials.Show less

Improper authentication in Veeam Backup & Replication 9.5U3, 9.5U4,10.x and 11.x component used for Microsoft System Center Virtual Machine Manager (SCVMM) allows attackers execute arbitrary code via Veeam.Backup.PSManager.exeShow less

Volto is a ReactJS-based frontend for the Plone Content Management System. Between versions 14.0.0-alpha.5 and 15.0.0-alpha.0, a user could have their authentication cookie replaced with an authentication cookie from another user, effectively giving them control of the other user's account and privileges. This occurs when using an outdated version of the `react-cookie` library and a server is under high load. A proof of concept does not currently exist, but it is possible for this issue to occur in the wild. The patch and fix is present in Volto 15.0.0-alpha.0. As a workaround, one may manually upgrade the `react-cookie` package to 4.1.1 and then override all Volto components that use this library.Show less

An issue was discovered in OpenSSH before 8.9. If a client is using public-key authentication with agent forwarding but without -oLogLevel=verbose, and an attacker has silently modified the server to support the None authentication option, then the user cannot determine whether FIDO authentication is going to confirm that the user wishes to connect to that server, or that the user wishes to allow that server to connect to a different server on the user's behalf. NOTE: the vendor's position is "this is not an authentication bypass, since nothing is being bypassed.Show less

CAMS for HIS Server contained in the following Yokogawa Electric products improperly authenticate the receiving packets. The authentication may be bypassed via some crafted packets: CENTUM CS 3000 versions from R3.08.10 to R3.09.00, CENTUM VP versions from R4.01.00 to R4.03.00, from R5.01.00 to R5.04.20, and from R6.01.00 to R6.08.00, and Exaopc versions from R3.72.00 to R3.79.00.Show less

Acer QuickAccess 2.01.300x before 2.01.3030 and 3.00.30xx before 3.00.3038 contains a local privilege escalation vulnerability. The user process communicates with a service of system authority through a named pipe. In this case, the Named Pipe is also given Read and Write rights to the general user. In addition, the service program does not verify the user when communicating. A thread may exist with a specific command. When the path of the program to be executed is sent, there is a local privilege escalation in which the service program executes the path with system privileges.Show less

Acer Care Center 4.00.30xx before 4.00.3042 contains a local privilege escalation vulnerability. The user process communicates with a service of system authority called ACCsvc through a named pipe. In this case, the Named Pipe is also given Read and Write rights to the general user. In addition, the service program does not verify the user when communicating. A thread may exist with a specific command. When the path of the program to be executed is sent, there is a local privilege escalation in which the service program executes the path with system privileges.Show less

YzmCMS v6.3 is affected by broken access control. Without login, unauthorized access to the user's personal home page can be realized. It is necessary to judge the user's login status before accessing the personal home page, but the vulnerability can access other users' home pages through the non login status because real authentication is not carried out.Show less
