url /cgi-bin/Maconomy/MaconomyWS.macx1.W_MCS//etc/passwd↗

path /cgi-bin/Maconomy/MaconomyWS.macx1.W_MCS//etc/passwd↗

• → Detect LFI exploitation attempts against Deltek Maconomy by monitoring HTTP GET requests to the path pattern /cgi-bin/Maconomy/MaconomyWS.macx1.W_MCS/ followed by an absolute path traversal (e.g., //etc/passwd). The double-slash before the traversal path is characteristic of this exploit. ↗
• → A successful exploitation response will contain the string matching 'root:.*:0:0:' in the HTTP response body with a 200 status code, indicating /etc/passwd file contents were returned. ↗
• → Monitor for HTTP GET requests targeting the CGI endpoint /cgi-bin/Maconomy/MaconomyWS.macx1.W_MCS/ with PATH_INFO containing absolute paths (starting with //) as this is the exploitation vector. ↗

• · The vulnerability is specific to Deltek Maconomy version 2.2.5. Detection rules should be scoped to this version or validated against the CPE before alerting. ↗
