Sensitive data exposure via publicly accessible logs in upsshipping module from Agence Web 360 for PrestaShop
A sensitive data exposure vulnerability in the UPS Shipping Module (upsshipping) for PrestaShop, in all known versions up to and including 2.4.0, allows remote unauthenticated attackers to retrieve XML log files containing UPS API credentials, shipper account numbers and customer personal data through predictable URLs in the modules/upsshipping/logs/ directory. The vendor (Agence Web 360) is defunct and no patch will be released.
The modules/upsshipping/logs/ directory ships without any access control mechanism. There is no .htaccess file anywhere in the module, and the logs/ directory is the only subdirectory without the blank index.php guard. As a result, any file written to that directory is directly reachable over HTTP without authentication.
Filenames written by the module follow a deterministic pattern based on time():
UPSRatingApi-request-{unix_timestamp}.xml UPSShippingApi-request-{unix_timestamp}.xml UPSTrackingApi-request-{unix_timestamp}.xml
(and their -response- counterparts). Enumeration of historical files is therefore trivial.
In lib/UPSBaseApi.php, the catch (Exception $e) block of the SOAP call writes the full request and response to disk unconditionally, regardless of the $this->log debug flag. Every UPS API error (invalid tracking number, timeout, validation rejection, and so on) leaves a record on disk containing the full SOAP envelope, including the UPSSecurity header with the merchant’s UPS API credentials in clear text.
The clearLogs() routine intended to remove files older than 30 minutes does not run reliably. On a confirmed affected instance, the directory contained 2,381,841 XML files (~ 8.7 GB) spanning February 2023 to April 2026.
Example of the data exposed in a single request file (values redacted):
ns3:UsernameXXXXXX</ns3:Username> ns3:PasswordXXXXXX</ns3:Password> ns3:AccessLicenseNumberXXC2BB3311XXXXXX</ns3:AccessLicenseNumber> ns2:ShipperNumber3XYXXX</ns2:ShipperNumber> ns2:TaxIdentificationNumberFR00819XXXX</ns2:TaxIdentificationNumber> ns2:NameCustomer Name</ns2:Name> ns2:Phonens2:Number460768XXXXXX</ns2:Number></ns2:Phone> ns2:AddressLineVästervägen XX</ns2:AddressLine> ns2:CityVindeln</ns2:City> ns2:PostalCode922 31</ns2:PostalCode> ns2:CountryCodeSE</ns2:CountryCode>
A secondary weakness exists in lib/UPSLocatorApi.php, where TLS certificate validation is disabled (CURLOPT_SSL_VERIFYPEER=0, CURLOPT_SSL_VERIFYHOST=0), enabling man-in-the-middle interception of Locator API traffic (CWE-295).
The vendor (Agence Web 360, Golfe-Juan, France) is confirmed defunct: the domain agence-web-360.com is listed for sale, the Facebook page has been inactive since 2016, and prior contact attempts over the past years received no response. The module is no longer maintained and no fix will be released.
