SPIP 1.9 before 1.9.2i and 2.0.x through 2.0.8 does not use proper access control for (1) ecrire/exec/install.php and (2) ecrire/index.php, which allows remote attackers to conduct unauthorized activities related to installation and backups, as exploited in the wild in August 2009.

  • →Detect unauthenticated GET requests to the SPIP install endpoint with the reinstall and transformer_xml parameters, which indicate exploitation of the missing access control. ↗
  • →Flag path traversal sequences (../../../IMG/) in the nom_sauvegarde parameter of requests to ecrire/?exec=install, indicating an attempt to write backup/export files outside the intended directory. ↗
  • →Monitor POST requests to spip.php containing action=export_all and export[]=spip_auteurs, which are used to exfiltrate the authors/credentials table via the backup mechanism. ↗
  • →Alert on unauthenticated access to ecrire/exec/install.php or ecrire/index.php from external IPs, as these endpoints should require authentication. ↗
  • →Detect retrieval of .xml files from the IMG/ directory immediately following install endpoint requests, indicating successful data exfiltration via the backup export chain. ↗
  • ·The vulnerability affects SPIP 1.9 before 1.9.2i and 2.0.x through 2.0.8 only; versions 2.0.9 and later are patched. Ensure detection rules are scoped to vulnerable version ranges to reduce false positives. ↗
  • ·The exploit was confirmed exploited in the wild as of August 2009; treat any detections on legacy SPIP installations as high-confidence active exploitation. ↗
