Missing Authentication for Critical Function in the Bosch Video Streaming Gateway (VSG) allows an unauthenticated remote attacker to retrieve and set arbitrary configuration data of the Video Streaming Gateway. A successful attack can impact the confidentiality and availability of live and recorded video data of all cameras configured to be controlled by the VSG as well as the recording storage associated with the VSG. This affects Bosch Video Streaming Gateway versions 6.45 <= 6.45.08, 6.44 <= 6.44.022, 6.43 <= 6.43.0023 and 6.42.10 and older. This affects Bosch DIVAR IP 3000, DIVAR IP 7000 and DIVAR IP all-in-one 5000 if a vulnerable VSG version is installed with BVMS. This affects Bosch DIVAR IP 2000 <= 3.62.0019 and DIVAR IP 5000 <= 3.80.0039 if the corresponding port 8023 has been opened in the device's firewall.

Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.

A recently discovered security vulnerability affects all Bosch Video Management System (BVMS) versions 9.0 and below, DIVAR IP 2000, 3000, 5000 and 7000, Video Recording Manager (VRM), Video Streaming Gateway (VSG), Configuration Manager, Building Integration System (BIS) with Video Engine, Access Professional Edition (APE), Access Easy Controller (AEC), Bosch Video Client (BVC) and Video SDK (VSDK). The vulnerability potentially allows the unauthorized execution of code in the system via the network interface.

If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).

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.

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.

In ABB IP GATEWAY 3.39 and prior, some configuration files contain passwords stored in plain-text, which may allow an attacker to gain unauthorized access.

In ABB IP GATEWAY 3.39 and prior, the web server does not sufficiently verify that a request was performed by the authenticated user, which may allow an attacker to launch a request impersonating that user.

In ABB IP GATEWAY 3.39 and prior, by accessing a specific uniform resource locator (URL) on the web server, a malicious user is able to access the configuration files and application pages without authentication.
