A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0 SP1). Some parts of the web application are not protected against Cross Site Request Forgery (CSRF) attacks. The security vulnerability could be exploited by an attacker that is able to trigger requests of a logged-in user to the application. The vulnerability could allow switching the connectivity state of a user or a device. At the time of advisory publication no public exploitation of this security vulnerability was known.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V2.0 SP1). Some pages that should only be accessible by a privileged user can also be accessed by a non-privileged user. The security vulnerability could be exploited by an attacker with network access and valid credentials for the web interface. No user interaction is required. The vulnerability could allow an attacker to access information that he should not be able to read. The affected information does not include passwords. At the time of advisory publication no public exploitation of this security vulnerability was known.

The vulnerability could be exploited by an attacker with network access to the vulnerable software, requiring no privileges and no user interaction. The vulnerability could allow full access to the web interface. At the time of advisory publication no public exploitation of this security vulnerability was known.

The Linux kernel, versions 3.9+, IP implementation is vulnerable to denial of service conditions with low rates of specially modified packets

The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size.

A vulnerability has been identified in SINEMA Remote Connect Client (All versions < V3.2 SP2). The affected application inserts sensitive information into a log file which is readable by all legitimate users of the underlying system. This could allow an authenticated attacker to compromise the confidentiality of other users' configuration data.

A vulnerability has been identified in SINEMA Remote Connect Server (All versions < V3.2 SP2). The affected application does not properly handle user session establishment and invalidation. This could allow a remote attacker to circumvent the additional multi factor authentication for user session establishment.
