This allows authenticated attackers to store backups in arbitrary folders on the server provided they can be written to by the server. Additionally, default settings will place an index.php and a .htaccess file into the chosen directory (unless already present) when the first backup job is run that are intended to prevent directory listing and file access. This means that an attacker could set the backup directory to the root of another site in a shared environment and thus disable that site.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H","score":6.8},"cwes":["CWE-22"],"references":["https://plugins.trac.wordpress.org/browser/backwpup/trunk/inc/class-page-editjob.php?rev=2818974#L29","https://plugins.trac.wordpress.org/changeset/3000176/backwpup/trunk/inc/class-destination-folder.php","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=2980789%40backwpup%2Ftrunk&old=2954541%40backwpup%2Ftrunk&sfp_email=&sfph_mail=","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3000176%40backwpup&new=3000176%40backwpup&sfp_email=&sfph_mail=","https://www.wordfence.com/threat-intel/vulnerabilities/id/98085a23-0cb6-442a-a28a-cb5c2890b60d?source=cve"],"products":["inpsyde:backwpup"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2023-5505","score":0.00981,"percentile":0.62259,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
