Secure Guest Data and Booking Platforms

Travel and Hospitality: A Data-Rich Target

The travel and hospitality industry collects an exceptionally broad range of personal data. A single hotel reservation might include the guest's full name, home address, email, phone number, passport number, credit card details, travel dates, companion names, loyalty membership, and special requests (which can reveal medical conditions or dietary restrictions). Airline bookings add passport numbers, visa information, and frequent flyer data.

This breadth of data, combined with the industry's massive transaction volumes and global reach, makes travel and hospitality platforms persistently attractive targets. The Marriott breach exposed 500 million guest records. British Airways was fined 20 million GBP for a payment card skimming attack on their booking website. These incidents demonstrate that the web application layer is where hospitality breaches occur.

Booking Engine Vulnerabilities

The booking engine is the revenue core of any travel platform. It handles availability searches, rate calculations, room or seat selection, personal data collection, and payment processing. Each step in this flow is an attack opportunity.

APVISO's agents test booking engines comprehensively:

• Price manipulation: Modifying rate codes, room types, or date parameters between search and confirmation to obtain lower prices
• Availability bypass: Accessing inventory that should be blocked, sold out, or restricted to certain channels
• Promotional abuse: Exploiting discount code logic for unauthorized discounts, stacking, or reuse
• Data exposure: Checking whether booking confirmation APIs return excessive data about other guests or reservations
• Payment handling: Testing the integration between the booking engine and payment processor for data leakage and manipulation

The lead agent coordinates these tests as an integrated workflow, ensuring that the booking process is tested end-to-end rather than as isolated API calls.

Loyalty Programs Are Currency

Hotel and airline loyalty points have direct monetary value. Marriott Bonvoy points, Hilton Honors points, and airline miles can be redeemed for stays, flights, and transferred to partners. This makes loyalty programs attractive targets for account takeover and business logic exploitation.

Attack patterns against loyalty programs include:

• Account takeover: Credential stuffing against loyalty login portals to hijack accounts with high point balances
• Point transfer exploitation: Business logic flaws that allow unauthorized point transfers between accounts
• Redemption manipulation: Exploiting redemption flows to redeem points at incorrect rates or for unauthorized benefits
• Status manipulation: Modifying elite status or tier qualifications through API parameter tampering
• Point generation: Logic flaws that create points without corresponding qualifying activity

APVISO tests all of these patterns. The scanner agent exercises loyalty program APIs for authentication, authorization, and business logic flaws that could enable point theft or account compromise.

Property Management System Exposure

Modern property management systems (PMS) are web applications that manage reservations, guest check-in/out, room assignments, housekeeping, billing, and integrations with door lock systems, point-of-sale terminals, and third-party booking channels. The web interfaces for these systems are increasingly accessible remotely, expanding the attack surface beyond the property network.

APVISO tests PMS web interfaces for:

• Authentication and access control between different staff roles
• Guest data isolation across properties in multi-hotel deployments
• Integration security with channel managers and OTA connections
• Administrative functionality including rate management and configuration

Multi-Channel Booking Security

Hotels and airlines receive bookings through multiple channels: direct websites, mobile apps, OTAs (Booking.com, Expedia), GDS connections, and travel agent portals. Each channel connects to the central reservation system through APIs. Vulnerabilities in any channel's API integration can expose the central system.

APVISO tests the APIs that connect booking channels to your central system, identifying authentication weaknesses, data exposure through channel-specific endpoints, and authorization flaws that could allow one channel partner to access data from another.

Seasonal Readiness

The travel industry is seasonal. Hotels have peak booking seasons. Airlines have holiday travel rushes. These periods generate the most revenue and the most transaction volume, making them the worst time to discover a vulnerability.

APVISO enables proactive security testing before peak seasons. Run comprehensive scans during the low season, remediate findings, and verify fixes before the booking rush begins. Scheduling capabilities mean you can establish a recurring testing cadence that ensures continuous coverage throughout the year.

Protect Your Guests

Guest trust is the foundation of the hospitality industry. Travelers share their most sensitive information because they trust that it will be protected. APVISO helps you honor that trust by finding and fixing the vulnerabilities that put guest data at risk. Start scanning today and ensure your booking platform, loyalty program, and property systems are secure.
