Online Shopping System Injection and XSS Flaws

SQL injection in code-projects Online Shopping System 1.0 allows remote unauthenticated attackers to manipulate the email parameter on the /login.php endpoint, potentially bypassing authentication and reading or modifying backend database contents. A public proof-of-concept exploit has been published on GitHub, confirming practical exploitability. No patch is available at time of analysis, and the product is a low-prevalence academic/demo codebase with no indication of CISA KEV listing.

SQL injection in code-projects Online Shopping System 1.0 exposes the `/action.php` endpoint to database manipulation via the unsanitized `proId` parameter. Attackers with low-privilege application access can send crafted HTTP requests over the network to read, alter, or corrupt backend database contents - impacting confidentiality, integrity, and availability. Publicly available exploit code exists per the GitHub disclosure, significantly lowering the skill barrier for opportunistic attackers despite the low CVSS 4.0 base score of 2.1.

SQL injection in the `cat_id` parameter of `/homeaction.php` in code-projects Online Shopping System 1.0 exposes the backend database to remote attackers holding low-privilege authenticated sessions. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L) confirms low-complexity network exploitation with a public proof-of-concept documented on GitHub, lowering the skill bar for abuse. Successful exploitation yields limited read, write, and availability impact against the application's database; no public active exploitation (KEV) has been confirmed.

SQL injection in code-projects Online Shopping System 1.0 allows remote low-privileged attackers to manipulate the `total_count` parameter in `/checkout_process.php` to execute arbitrary SQL commands against the backend database. The CVSS 4.0 score is 5.3 (Medium) with partial confidentiality, integrity, and availability impact; no subsequent-system scope change is indicated. A public proof-of-concept exploit is available on GitHub, substantially lowering the bar for opportunistic exploitation - though the product's niche footprint limits broad real-world blast radius.

Cross-site scripting in code-projects Online Shopping System 1.0 allows remote low-privileged attackers to inject arbitrary JavaScript into victim browsers via the unsanitized `amount_1` parameter in `/checkout.php`, enabling session hijacking, credential theft, or UI manipulation against users who interact with the crafted response. The affected product is a PHP-based e-commerce application distributed by code-projects.org, with the vulnerability tracked exclusively through VulDB. A public proof-of-concept exploit has been released on GitHub, elevating the practical risk beyond the moderate CVSS 4.0 score of 5.1 suggests in isolation.
