CVSS v3.1 |
| An exploitable denial-of-service vulnerability exists in Systemd 245. A specially crafted DHCP FORCERENEW packet can cause a server running the DHCP client to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHP ACK packets to reconfigure the server. |
| An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). |
| A vulnerability was discovered in vdsm, version 4.19 through 4.30.3 and 4.30.5 through 4.30.8. The systemd_run function exposed to the vdsm system user could be abused to execute arbitrary commands as root. |
| A memory leak was discovered in the backport of fixes for CVE-2018-16864 in Red Hat Enterprise Linux. Function dispatch_message_real() in journald-server.c does not free the memory allocated by set_iovec_field_free() to store the `_CMDLINE=` entry. A local attacker may use this flaw to make systemd-journald crash. This issue only affects versions shipped with Red Hat Enterprise since v219-62.2. |
| Signal Desktop before 1.29.1 on Windows allows local users to gain privileges by creating a Trojan horse %SYSTEMDRIVE%\node_modules\.bin\wmic.exe file. |
| In IXP EasyInstall 6.2.13723, there is Lateral Movement (using the Agent Service) against other users on a client system. An authenticated attacker can, by modifying %SYSTEMDRIVE%\IXP\SW\[PACKAGE_CODE]\EveryLogon.bat, achieve this movement and execute code in the context of other users. |
| In IXP EasyInstall 6.2.13723, it is possible to temporarily disable UAC by using the Agent Service on a client system. An authenticated attacker (non-admin) can disable UAC for other users by renaming and replacing %SYSTEMDRIVE%\IXP\DATA\IXPAS.IXP. |
| A UNIX Symbolic Link (Symlink) Following vulnerability in the mysql-systemd-helper of the mariadb packaging of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15 allows local attackers to change the permissions of arbitrary files to 0640. This issue affects: SUSE Linux Enterprise Server 12 mariadb versions prior to 10.2.31-3.25.1. SUSE Linux Enterprise Server 15 mariadb versions prior to 10.2.31-3.26.1. |
| In systemd 240, bus_open_system_watch_bind_with_description in shared/bus-util.c (as used by systemd-resolved to connect to the system D-Bus instance), calls sd_bus_set_trusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that should be restricted to privileged users, in order to change the system's DNS resolver settings. |
| An issue was discovered in Microvirt MEmu all versions prior to 7.0.2. A guest Android operating system inside the MEmu emulator contains a /system/bin/systemd binary that is run with root privileges on startup (this is unrelated to Red Hat's systemd init program, and is a closed-source proprietary tool that seems to be developed by Microvirt). This program opens TCP port 21509, presumably to receive installation-related commands from the host OS. Because everything after the installer:uninstall command is concatenated directly into a system() call, it is possible to execute arbitrary commands by supplying shell metacharacters. |
| Multiple Zoho ManageEngine products suffer from local privilege escalation due to improper permissions for the %SYSTEMDRIVE%\ManageEngine directory and its sub-folders. Moreover, the services associated with said products try to execute binaries such as sc.exe from the current directory upon system start. This will effectively allow non-privileged users to escalate privileges to NT AUTHORITY\SYSTEM. This affects Desktop Central 10.0.380, EventLog Analyzer 12.0.2, ServiceDesk Plus 10.0.0, SupportCenter Plus 8.1, O365 Manager Plus 4.0, Mobile Device Manager Plus 9.0.0, Patch Connect Plus 9.0.0, Vulnerability Manager Plus 9.0.0, Patch Manager Plus 9.0.0, OpManager 12.3, NetFlow Analyzer 11.0, OpUtils 11.0, Network Configuration Manager 11.0, FireWall 12.0, Key Manager Plus 5.6, Password Manager Pro 9.9, Analytics Plus 1.0, and Browser Security Plus. |
| A vulnerability was found in libvirt >= 4.1.0 in the virtlockd-admin.socket and virtlogd-admin.socket systemd units. A missing SocketMode configuration parameter allows any user on the host to connect using virtlockd-admin-sock or virtlogd-admin-sock and perform administrative tasks against the virtlockd and virtlogd daemons. |
| Unquoted Windows search path vulnerability in NSClient++ before 0.4.1.73 allows non-privileged local users to execute arbitrary code with elevated privileges on the system via a malicious program.exe executable in the %SYSTEMDRIVE% folder. |
| systemd 239 through 245 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication (SNI) is not sent, and there is no hostname validation with the GnuTLS backend. NOTE: This has been disputed by the developer as not a vulnerability since hostname validation does not have anything to do with this issue (i.e. there is no hostname to be sent) |
| Spring Boot supports an embedded launch script that can be used to easily run the application as a systemd or init.d linux service. The script included with Spring Boot 1.5.9 and earlier and 2.0.0.M1 through 2.0.0.M7 is susceptible to a symlink attack which allows the "run_user" to overwrite and take ownership of any file on the same system. In order to instigate the attack, the application must be installed as a service and the "run_user" requires shell access to the server. Spring Boot application that are not installed as a service, or are not using the embedded launch script are not susceptible. |
| In systemd prior to 234 a race condition exists between .mount and .automount units such that automount requests from kernel may not be serviced by systemd resulting in kernel holding the mountpoint and any processes that try to use said mount will hang. A race condition like this may lead to denial of service, until mount points are unmounted. |
| An issue was discovered in UCMS 1.4.6 and 1.6. It allows PHP code injection during installation via the systemdomain parameter to install/index.php, as demonstrated by injecting a phpinfo() call into /inc/config.php. |
| It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable. |
| systemd-tmpfiles in systemd before 237 attempts to support ownership/permission changes on hardlinked files even if the fs.protected_hardlinks sysctl is turned off, which allows local users to bypass intended access restrictions via vectors involving a hard link to a file for which the user lacks write access, as demonstrated by changing the ownership of the /etc/passwd file. |
| In snapd 2.27 through 2.29.2 the 'snap logs' command could be made to call journalctl without match arguments and therefore allow unprivileged, unauthenticated users to bypass systemd-journald's access restrictions. |
