A function call could result in a log forging attack. Writing untrusted data into a log file allows an attacker to forge log entries or inject malicious content into log files. Corrupted log files can be used to cover an attacker's tracks or as a delivery mechanism for an attack on a log viewing or processing utility. For example, if a web administrator uses a browser-based utility to review logs, a cross-site scripting attack might be possible. - added a new java class to neutralize logs output - imported esapi library to encode logs for html output - override log4j to use new custom layout class as the layout pattern for share.log

I believe the same comments apply here as do from @skopf on the sibling PR for the remote-api project - see Alfresco/alfresco-remote-api#145 (comment) |
