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 dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j).

The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

When uploading a file in Sysax Multi Server 6.90, an authenticated user can modify the filename="" parameter in the uploadfile_name1.htm form to a length of 368 or more bytes. This will create a buffer overflow condition, causing the application to crash.

An issue was discovered in Sysax Multi Server 6.90. A session can be hijacked if one observes the sid value in any /scgi URI, because it is an authentication token.

An issue was discovered in Sysax Multi Server 6.90. An attacker can determine the username (under which the web server is running) by triggering an invalid path permission error. This bypasses the fakepath protection mechanism.

An issue was discovered in Sysax Multi Server 6.90. There is reflected XSS via the /scgi sid parameter.

The Quick Heal AV parsing engine (November 2019) allows virus-detection bypass via a crafted GPFLAG in a ZIP archive. This affects Total Security, Home Security, Total Security Multi-Device, Internet Security, Total Security for Mac, AntiVirus Pro, AntiVirus for Server, and Total Security for Android.

JasperReports library components contain an information disclosure vulnerability. This vulnerability includes the theoretical disclosure of any accessible information from the host file system. Affects TIBCO JasperReports Library Community Edition (versions 6.4.0 and below), TIBCO JasperReports Library for ActiveMatrix BPM (versions 6.2.0 and below), TIBCO JasperReports Professional (versions 6.2.1 and below, and 6.3.0), TIBCO JasperReports Server (versions 6.1.1 and below, 6.2.0, 6.2.1, 6.3.0), TIBCO JasperReports Server Community Edition (versions 6.3.0 and below), TIBCO JasperReports Server for ActiveMatrix BPM (versions 6.2.0 and below), TIBCO Jaspersoft for AWS with Multi-Tenancy (versions 6.3.0 and below), TIBCO Jaspersoft Reporting and Analytics for AWS (versions 6.3.0 and below), and TIBCO Jaspersoft Studio for ActiveMatrix BPM (versions 6.2.0 and below).

Stack-based buffer overflow in Sysax Multi Server before 5.52, when HTTP is enabled, allows remote authenticated users with the create folder permission to execute arbitrary code via a crafted request.

Directory traversal vulnerability in Sysax Multi Server 4.3 and 4.5 allows remote authenticated users to delete arbitrary files via a ..// (dot dot slash slash) in a DELE command.
