Vulnerabilities

An issue was discovered in Zammad 3.0 through 3.2. The WebSocket server crashes when messages in non-JSON format are sent by an attacker. The message format is not properly checked and parsing errors not handled. This leads to a crash of the service process.

An issue was discovered in Centreon before 2.8-30,18.10-8, 19.04-5, and 19.10-2. It provides sensitive information via an unauthenticated direct request for include/monitoring/recurrentDowntime/GetXMLHost4Services.php.

An issue was discovered in Centreon before 2.8-30, 18.10-8, 19.04-5, and 19.10-2.. It provides sensitive information via an unauthenticated direct request for include/configuration/configObject/host/refreshMacroAjax.php.

CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.

HPE OneView Global Dashboard (OVGD) 1.9 has a remote information disclosure vulnerability. HPE OneView Global Dashboard - After Upgrade or Install of OVGD Version 1.9, Appliance Firewall May Leave Ports Open. This is resolved in OVGD 1.91 or later.

CNCF Envoy through 1.13.0 may consume excessive amounts of memory when responding internally to pipelined requests.

CNCF Envoy through 1.13.0 has incorrect Access Control when using SDS with Combined Validation Context. Using the same secret (e.g. trusted CA) across many resources together with the combined validation context could lead to the “static” part of the validation context to be not applied, even though it was visible in the active config dump.

CNCF Envoy through 1.13.0 may consume excessive amounts of memory when proxying HTTP/1.1 requests or responses with many small (i.e. 1 byte) chunks.

Multiple ZyXEL network-attached storage (NAS) devices running firmware version 5.21 contain a pre-authentication command injection vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable device. ZyXEL NAS devices achieve authentication by using the weblogin.cgi CGI executable. This program fails to properly sanitize the username parameter that is passed to it. If the username parameter contains certain characters, it can allow command injection with the privileges of the web server that runs on the ZyXEL device. Although the web server does not run as the root user, ZyXEL devices include a setuid utility that can be leveraged to run any command with root privileges. As such, it should be assumed that exploitation of this vulnerability can lead to remote code execution with root privileges. By sending a specially-crafted HTTP POST or GET request to a vulnerable ZyXEL device, a remote, unauthenticated attacker may be able to execute arbitrary code on the device. This may happen by directly connecting to a device if it is directly exposed to an attacker. However, there are ways to trigger such crafted requests even if an attacker does not have direct connectivity to a vulnerable devices. For example, simply visiting a website can result in the compromise of any ZyXEL device that is reachable from the client system. Affected products include: NAS326 before firmware V5.21(AAZF.7)C0 NAS520 before firmware V5.21(AASZ.3)C0 NAS540 before firmware V5.21(AATB.4)C0 NAS542 before firmware V5.21(ABAG.4)C0 ZyXEL has made firmware updates available for NAS326, NAS520, NAS540, and NAS542 devices. Affected models that are end-of-support: NSA210, NSA220, NSA220+, NSA221, NSA310, NSA310S, NSA320, NSA320S, NSA325 and NSA325v2

Rubetek SmartHome 2020 devices use unencrypted 433 MHz communication between controllers and beacons, allowing an attacker to sniff and spoof beacon requests remotely.

ARRIS TG1692A devices allow remote attackers to discover the administrator login name and password by reading the /login page and performing base64 decoding.

An issue was discovered on HUMAX HGA12R-02 BRGCAA 1.1.53 devices. A vulnerability in the authentication functionality in the web-based interface could allow an unauthenticated remote attacker to capture packets at the time of authentication and gain access to the cleartext password. An attacker could use this access to create a new user account or control the device.
