![]() ![]() ![]() We can confirm that DRAM devices acquired in July 2020 with DRAM chips from all three major DRAM vendors (Samsung, SK Hynix, Micron) are affected by this vulnerability. For example, this enables privilege-escalation attacks against the kernel or binaries such as the sudo binary, and also triggering bit flips in RSA-2048 keys (e.g., SSH keys) to gain cross-tenant virtual-machine access. This means that, even when chips advertised as Rowhammer-free are used, attackers may still be able to exploit Rowhammer. The patterns generated by Blacksmith were able to trigger bitflips on all 40 PC-DDR4 DRAM devices in our test pool, which cover the three major DRAM manufacturers: Samsung, SK Hynix, and Micron. Novel non-uniform Rowhammer access patterns, consisting of aggressors with different frequencies, phases, and amplitudes allow triggering bit flips on affected memory modules using our Blacksmith fuzzer. Modern DRAM devices (PC-DDR4, LPDDR4X) are affected by a vulnerability in their internal Target Row Refresh (TRR) mitigation against Rowhammer attacks. #USING A .PEM ROYAL TS PASSWORD#This enables an attacker to gain control of the device through SSH (regardless of whether the admin password was changed on the web interface). The root SSH password never gets updated from its default value of admin. The Yubico YubiHSM YubiHSM2 library 2021.08, included in the yubihsm-shell project, does not properly validate the length of some operations including SSH signing requests, and some data operations received from a YubiHSM 2 device.Īn issue was discovered on Victure WR1200 devices through 1.0.3. World-writable permissions on the /tmp/tmate/sessions directory in tmate-ssh-server 2.3.0 allow a local attacker to compromise the integrity of session handling, or obtain the read-write session ID from a read-only session symlink in this directory. Insecure creation of temporary directories in tmate-ssh-server 2.3.0 allows a local attacker to compromise the integrity of session handling. NOTE: the vendor does not agree that this is a vulnerability however, addon.stdin was removed as a defense-in-depth measure against complex social engineering situations. ** DISPUTED ** The addon.stdin service in addon-ssh (aka Home Assistant Community Add-on: SSH & Web Terminal) before 10.0.0 has an attack surface that requires social engineering. ![]() Under a specific update-migration scenario, the first SSH password change does not properly clear the old password. Missing permission checks in Jenkins SSH Agent Plugin 1.23 and earlier allows attackers with Overall/Read access to enumerate credentials IDs of credentials stored in Jenkins.Īn issue was discovered in Stormshield Network Security (SNS) 4.2.2 through 4.2.7 (fixed in 4.2.8). Jenkins Publish Over SSH Plugin 1.22 and earlier does not escape the SSH server name, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission. Jenkins Publish Over SSH Plugin 1.22 and earlier performs a validation of the file name specifying whether it is present or not, resulting in a path traversal vulnerability allowing attackers with Item/Configure permission to discover the name of the Jenkins controller files.Ī missing permission check in Jenkins Publish Over SSH Plugin 1.22 and earlier allows attackers with Overall/Read access to connect to an attacker-specified SSH server using attacker-specified credentials.Ī cross-site request forgery (CSRF) vulnerability in Jenkins Publish Over SSH Plugin 1.22 and earlier allows attackers to connect to an attacker-specified SSH server using attacker-specified credentials. Jenkins Publish Over SSH Plugin 1.22 and earlier stores password unencrypted in its global configuration file on the Jenkins controller where it can be viewed by users with access to the Jenkins controller file system. #USING A .PEM ROYAL TS CODE#Code execution can, for example, use the -gtk-module option. USBView 2.1 before 2.2 allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allow_any=yes) for pkexec disable the authentication requirement. ![]()
