  • Detect LFI exploitation attempts against iPECS NMS by monitoring GET requests to /ipecs-cm/download with 'filename' or 'filepath' parameters containing directory traversal sequences (../).
  • A null-byte injection variant is used in the filepath parameter (%00.jpg) to bypass file extension checks — monitor for %00 in query parameters targeting /ipecs-cm/download.
  • Successful exploitation returns HTTP 200 with /etc/passwd content matching 'root:[x*]:0:0' — alert on this pattern in HTTP responses from the iPECS NMS application.
  • The known fixed filepath anchor used in exploitation is /home/wms/www/data — presence of this string in HTTP requests to /ipecs-cm/download is a strong indicator of CVE-2018-15138 exploitation.
  • ·Two distinct attack vectors exist: one traverses via the 'filename' parameter with a fixed 'filepath', and the other traverses via the 'filepath' parameter using a null-byte (%00) extension bypass. Detection rules should cover both patterns independently.
  • ·The template uses stop-at-first-match across two requests, meaning real-world exploitation may only generate one of the two request patterns — do not rely on seeing both requests to confirm exploitation.
