A URL redirection vulnerability in Skyhigh SWG in main releases 10.x prior to 10.2.9, 9.x prior to 9.2.20, 8.x prior to 8.2.27, and 7.x prior to 7.8.2.31, and controlled release 11.x prior to 11.1.3 allows a remote attacker to redirect a user to a malicious website controlled by the attacker. This is possible because…

A vulnerability in the Cisco Umbrella Secure Web Gateway service could allow an unauthenticated, remote attacker to bypass the file inspection feature. This vulnerability is due to insufficient restrictions in the file inspection feature. An attacker could exploit this vulnerability by downloading a crafted payload…

The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict…

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…

Privilege Escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows authenticated user interface user to delete or download protected log data via improper access controls in the user interface.

Privilege Escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows authenticated user interface user to delete or download protected files via improper access controls in the REST interface.

Privilege Escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows authenticated user interface user with low permissions to change the system's root password via improper access controls in the user interface.

Inappropriate Encoding for output context vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows a remote attacker to cause MWG to return an ambiguous redirect response via getting a user to click on a malicious URL.

The Sophos AV parsing engine before 2020-01-14 allows virus-detection bypass via a crafted ZIP archive. This affects Endpoint Protection, Cloud Optix, Mobile, Intercept X Endpoint, Intercept X for Server, and Secure Web Gateway. NOTE: the vendor feels that this does not apply to endpoint-protection products because…

Reflected Cross Site Scripting vulnerability in Administrators web console in McAfee Web Gateway (MWG) 7.8.x prior to 7.8.2.13 allows remote attackers to collect sensitive information or execute commands with the MWG administrator's credentials via tricking the administrator to click on a carefully constructed…

McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9517, potentially leading to a denial of service. This affects the scanning proxies.

McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9511, potentially leading to a denial of service. This affects the scanning proxies.

Clickjack vulnerability in Adminstrator web console in McAfee Web Gateway (MWG) 7.8.2.x prior to 7.8.2.12 allows remote attackers to conduct clickjacking attacks via a crafted web page that contains an iframe via does not send an X-Frame-Options HTTP header.

Exfiltration of Data in McAfee Web Gateway (MWG) 7.8.2.x prior to 7.8.2.12 allows attackers to obtain sensitive data via crafting a complex webpage that will trigger the Web Gateway to block the user accessing an iframe.

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each…
