CVE-2022-23073 in Recipes
Summary
by MITRE • 06/21/2022
In Recipes, versions 1.0.5 through 1.2.5 are vulnerable to Stored Cross-Site Scripting (XSS), in copy to clipboard functionality. When a victim accesses the food list page, then adds a new Food with a malicious javascript payload in the ‘Name’ parameter and clicks on the clipboard icon, an XSS payload will trigger. A low privileged attacker will have the victim's API key and can lead to admin's account takeover.

The vulnerability identified as CVE-2022-23073 affects the Recipes application within versions 1.0.5 through 1.2.5, presenting a critical stored cross-site scripting flaw that undermines user security and application integrity. This vulnerability specifically manifests within the copy to clipboard functionality, where user input is not properly sanitized or validated before being stored and subsequently rendered back to users. The flaw creates a persistent security risk where malicious actors can inject javascript payloads into the application's database through the food list management interface.
The technical implementation of this vulnerability occurs when a malicious user accesses the food list page and creates a new food item with a specially crafted javascript payload embedded within the 'Name' parameter field. When another user subsequently clicks the clipboard icon associated with this malicious food item, the stored payload executes within the victim's browser context. This stored XSS vector operates through the application's failure to properly escape or encode user-supplied data before it is persisted in the database and later displayed to other users. The vulnerability is particularly dangerous because it requires no user interaction beyond the initial malicious input, allowing the payload to execute automatically when users view the affected content.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to steal sensitive information including API keys from authenticated users. According to CWE-079, this represents a classic stored cross-site scripting vulnerability that allows attackers to execute malicious scripts in the context of a victim's browser session. The threat model suggests that a low privileged attacker with access to the application's food management features can leverage this vulnerability to compromise other users' sessions and potentially escalate privileges to administrative accounts. This represents a significant escalation path that violates the principle of least privilege and demonstrates poor input validation practices in the application's data handling pipeline.
The attack chain begins with a malicious user creating a food entry containing javascript payload in the name field, which is then stored in the application's database. When other users view this entry and interact with the clipboard functionality, their browsers execute the stored script, potentially stealing session cookies, API tokens, or other sensitive data. This vulnerability directly relates to ATT&CK technique T1531 which focuses on "Modify System Image" and T1566 which covers "Phishing", as it enables attackers to establish persistent access through malicious content injection. The impact is particularly severe because it operates silently in the background, allowing attackers to collect credentials and session information without requiring direct user interaction beyond the initial data injection.
Mitigation strategies should include implementing comprehensive input validation and output encoding mechanisms for all user-supplied data, particularly within fields that are later rendered back to users. The application should employ proper content security policies and implement strict sanitization of all data before storage, utilizing libraries such as DOMPurify or similar XSS prevention tools. Additionally, the application should implement proper session management and authentication controls, including token rotation and secure cookie attributes. Regular security audits should be conducted to identify similar vulnerabilities in other input fields, and the application should implement proper access controls to prevent low privilege users from injecting malicious content that could impact other users. The fix should also include rate limiting and monitoring for suspicious data injection patterns to prevent automated exploitation attempts.
