A vulnerability has been identified in SCALANCE M875 (All versions). An authenticated remote attacker with access to the web interface (443/tcp), could execute arbitrary operating system commands. Successful exploitation requires that the attacker has network access to the web interface. The attacker must be authenticated as administrative user to exploit the security vulnerability. The vulnerability could allow an attacker to execute arbitrary code on the device. At the time of advisory publication no public exploitation of this security vulnerability was known.

A vulnerability has been identified in SCALANCE M875 (All versions). The web interface on port 443/tcp could allow a Cross-Site Request Forgery (CSRF) attack if an unsuspecting user is tricked into accessing a malicious link. Successful exploitation requires user interaction by an legitimate user, who must be authenticated to the web interface as administrative user. A successful attack could allow an attacker to interact with the web interface as an administrative user. This could allow the attacker to read or modify the device configuration, or to exploit other vulnerabilities that require authentication as administrative user. At the time of advisory publication no public exploitation of this security vulnerability was known.
A vulnerability has been identified in SCALANCE M875 (All versions). An attacker with access to the local file system might obtain passwords for administrative users. Successful exploitation requires read access to files on the local file system. A successful attack could allow an attacker to obtain administrative passwords. At the time of advisory publication no public exploitation of this security vulnerability was known.
A vulnerability has been identified in SCALANCE M875 (All versions). An authenticated remote attacker with access to the web interface (443/tcp), could potentially read and download arbitrary files from the device's file system. Successful exploitation requires that the attacker has network access to the web interface. The attacker must be authenticated as administrative user to exploit the security vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.
A vulnerability has been identified in SCALANCE M875 (All versions). The web interface on port 443/tcp could allow a stored Cross-Site Scripting (XSS) attack if an unsuspecting user is tricked into accessing a malicious link. Successful exploitation requires that the attacker has access to the web interface of an affected device. The attacker must be authenticated as administrative user on the web interface. Afterwards, a legitimate user must access the web interface. A successful attack could allow an attacker to execute malicious code in the browser of a legitimate user. At the time of advisory publication no public exploitation of this security vulnerability was known.
An excessive resource consumption flaw was found in the way the Linux kernel's networking subsystem processed TCP Selective Acknowledgment (SACK) segments. While processing SACK segments, the Linux kernel's socket buffer (SKB) data structure becomes fragmented, which leads to increased resource utilization to traverse and process these fragments as further SACK segments are received on the same TCP connection. A remote attacker could use this flaw to cause a denial of service (DoS) by sending a crafted sequence of SACK segments on a TCP connection.
OpenBSD kernel version <= 6.5 can be forced to create long chains of TCP SACK holes that causes very expensive calls to tcpsackoption() for every incoming SACK packet which can lead to a denial of service.
