A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly limit the elevation of privileges required to perform certain valid functionality. This could allow an authenticated lowly-privileged remote attacker to escalate their privileges.

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions with SINEMA Remote Connect Edge Client installed). Affected devices do not properly sanitize configuration parameters. This could allow a non-privileged local attacker to execute root commands on the device.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0 HF0). Affected devices do not properly assign permissions to critical ressources. This could allow a non-privileged local attacker to interact with the backupmanager service.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly sanitize user input when creating new SNMP users. This could allow an authenticated highly-privileged remote attacker to execute arbitrary code on the device.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly sanitize user input when creating new VXLAN configurations. This could allow an authenticated highly-privileged remote attacker to execute arbitrary code on the device.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly limit the scope of files accessible through and the privileges of the SFTP functionality. This could allow an authenticated highly-privileged remote attacker to read and write arbitrary files.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0). Affected devices do not properly sanitize user input when creating new users. This could allow an authenticated highly-privileged remote attacker to execute arbitrary code on the device.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions with SINEMA Remote Connect Edge Client installed). Affected devices are vulnerable to an authentication bypass. This could allow a non-privileged local attacker to bypass the authentication of the SINEMA Remote Connect Edge Client, and to read and modify the configuration parameters.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0 HF0). Affected devices are vulnerable to a stack-based buffer overflow. This could allow a non-privileged local attacker to execute arbitrary code on the device or to cause a denial of service condition.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0 HF0). Affected devices are vulnerable to a stack-based buffer overflow. This could allow a non-privileged local attacker to execute arbitrary code on the device or to cause a denial of service condition.

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

Go before 1.15.15 and 1.16.x before 1.16.7 has a race condition that can lead to a net/http/httputil ReverseProxy panic upon an ErrAbortHandler abort.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0 HF0). Affected devices do not properly assign permissions to critical ressources. This could allow a non-privileged local attacker to access sensitive information stored on the device.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0 HF0). Affected devices are vulnerable to path traversal attacks. This could allow a privileged local attacker to restore backups that are outside the backup folder.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions with SINEMA Remote Connect Edge Client installed). Affected devices do transmit sensitive information in cleartext. This could allow a privileged local attacker to retrieve this sensitive information.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions < V4.0 HF0). Affected devices do not properly validate incoming Profinet packets. An unauthenticated remote attacker can exploit this flaw by sending a specially crafted malicious packet, which leads to a crash of the dcpd process.

A vulnerability has been identified in SCALANCE LPE9403 (6GK5998-3GS00-2AC2) (All versions). Affected devices do not properly handle multiple incoming Profinet packets received in rapid succession. An unauthenticated remote attacker can exploit this flaw by sending multiple packets in a very short time frame, which leads to a crash of the dcpd process.
