LibreOffice and OpenOffice automatically open embedded content

DjVuLibre 3.5.27 has a NULL pointer dereference in the function DJVU::filter_fv at IW44EncodeCodec.cpp.

LibreOffice documents can contain macros. The execution of those macros is controlled by the document security settings, typically execution of macros are blocked by default. A URL decoding flaw existed in how the urls to the macros within the document were processed and categorized, resulting in the possibility to…

An issue was discovered in LibreNMS 1.50.1. A SQL injection flaw was identified in the ajax_rulesuggest.php file where the term parameter is used insecurely in a database query for showing columns of a table, as demonstrated by an ajax_rulesuggest.php?debug=1&term= request.

An issue was discovered in LibreNMS 1.50.1. An authenticated user can perform a directory traversal attack against the /pdf.php file with a partial filename in the report parameter, to cause local file inclusion resulting in code execution.

An issue was discovered in LibreNMS 1.50.1. The scripts that handle graphing options (includes/html/graphs/common.inc.php and includes/html/graphs/graphs.inc.php) do not sufficiently validate or encode several fields of user supplied input. Some parameters are filtered with mysqli_real_escape_string, which is only…

An issue was discovered in LibreNMS through 1.47. It does not parameterize all user supplied input within database queries, resulting in SQL injection. An authenticated attacker can subvert these database queries to extract or manipulate data, as demonstrated by the graph.php sort parameter.

An issue was discovered in LibreNMS through 1.47. Many of the scripts rely on the function mysqli_escape_real_string for filtering data. However, this is particularly ineffective when returning user supplied input in an HTML or a JavaScript context, resulting in unsafe data being injected into these contexts, leading…

An issue was discovered in LibreNMS through 1.47. There is a command injection vulnerability in html/includes/graphs/device/collectd.inc.php where user supplied parameters are filtered with the mysqli_escape_real_string function. This function is not the appropriate function to sanitize command arguments as it does…

An issue was discovered in LibreNMS through 1.47. A number of scripts import the Authentication libraries, but do not enforce an actual authentication check. Several of these scripts disclose information or expose functions that are of a sensitive nature and are not expected to be publicly accessible.

An issue was discovered in LibreNMS through 1.47. Information disclosure can occur: an attacker can fingerprint the exact code version installed and disclose local file paths.
