Not invoking a call to `pam_acct_mgmt` after a call to `pam_authenticate` to check the validity of a login can lead to an authorization bypass. ### Impact #### Exploitability The attack can be carried over the network. A complex non-standard configuration or a specialized condition is required for the attack to be successfully conducted. The attacker also requires access to a users credentials, be it expired, for an attack to be successful. There is no user interaction required for successful execution. The attack can affect components outside the scope of the target module. #### Impact Using this attack vector, an attacker may access otherwise restricted parts of the system. The attack can be used to gain access to confidential files like passwords, login credentials and other secrets. Hence, it has a high impact on confidentiality. It may also be directly used to affect a change on a system resource. Hence has a medium to high impact on integrity. This attack may not be used to ...

GitHub has put out an advisory detailing what may be an ongoing phishing campaign targeting its users to steal credentials and two-factor authentication (2FA) codes by impersonating the CircleCI DevOps platform. The Microsoft-owned code hosting service said it learned of the attack on September 16, 2022, adding the campaign impacted "many victim organizations." The fraudulent messages claim to

A parsing vulnerability for the MessageSet type in the ProtocolBuffers versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 3.21.5 for protobuf-cpp, and versions prior to and including 3.16.1, 3.17.3, 3.18.2, 3.19.4, 3.20.1 and 4.21.5 for protobuf-python can lead to out of memory failures. A specially crafted message with multiple key-value per elements creates parsing issues, and can lead to a Denial of Service against services receiving unsanitized input. We recommend upgrading to versions 3.18.3, 3.19.5, 3.20.2, 3.21.6 for protobuf-cpp and 3.18.3, 3.19.5, 3.20.2, 4.21.6 for protobuf-python. Versions for 3.16 and 3.17 are no longer updated.

A now-patched critical security flaw affecting Atlassian Confluence Server that came to light a few months ago is being actively exploited for illicit cryptocurrency mining on unpatched installations. "If left unremedied and successfully exploited, this vulnerability could be used for multiple and more malicious attacks, such as a complete domain takeover of the infrastructure and the deployment

There are two primary methods available to remotely manage and administer a Red Hat Enterprise Linux (RHEL) system: the command line interface over an SSH connection and the RHEL web console.

An unpatched flaw in more than 350,000 unique open source repositories leaves software applications vulnerable to exploit. The path traversal-related vulnerability is tracked as CVE-2007-4559.

An unknown attacker targeted tens of thousands of unauthenticated Redis servers exposed on the internet in an attempt to install a cryptocurrency miner. It's not immediately known if all of these hosts were successfully compromised. Nonetheless, it was made possible by means of a "lesser-known technique" designed to trick the servers into writing data to arbitrary files – a case of unauthorized

The Linux-PAM package before 1.5.2-6.1 for openSUSE Tumbleweed allows authentication bypass for SSH logins. The pam_access.so module doesn't correctly restrict login if a user tries to connect from an IP address that is not resolvable via DNS. In such conditions, a user with denied access to a machine can still get access. NOTE: the relevance of this issue is largely limited to openSUSE Tumbleweed and openSUSE Factory; it does not affect Linux-PAM upstream.

PhotoSync version 4.7 suffers from a local file inclusion vulnerability.

Hello everyone! This video was recorded for the VMconf 22 Vulnerability Management conference, vmconf.pw. I will be talking about my open source project Scanvus.
