CVE-2006-1397 in phpPgAds
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in (a) phpAdsNew and (b) phpPgAds before 2.0.8 allow remote attackers to inject arbitrary web script or HTML via the (1) certain parameters to the banner delivery module, which is not properly handled in the administrator interface, or (2) certain parameters to the login form.

The vulnerability described in CVE-2006-1397 represents a critical cross-site scripting weakness affecting phpAdsNew and phpPgAds web applications prior to version 2.0.8. This flaw resides in the handling of user-supplied input within the banner delivery module and login form parameters, creating exploitable entry points that enable remote attackers to execute malicious scripts in the context of victim browsers. The vulnerability specifically impacts the administrative interface where improper sanitization of input parameters allows attackers to inject arbitrary HTML and JavaScript code that persists in the application's response to authenticated users.
The technical implementation of this vulnerability demonstrates a classic XSS attack vector where malicious input flows through the application's parameter handling mechanisms without adequate validation or encoding. When users interact with the banner delivery module or login form, the application fails to properly escape or validate input data before rendering it in web responses. This allows attackers to craft malicious payloads that are executed in the browser context of legitimate users who access the affected pages. The vulnerability affects both the banner delivery functionality and authentication mechanisms, providing attackers with multiple potential attack surfaces within the same application ecosystem.
From an operational perspective, this vulnerability poses significant risks to organizations utilizing these ad management platforms, as it enables attackers to hijack user sessions, steal sensitive information, and potentially escalate privileges within the administrative interface. The impact extends beyond simple script execution since the vulnerability affects the administrator interface, potentially allowing attackers to gain unauthorized access to critical system functions and modify advertising configurations. The persistence of these vulnerabilities in the delivery module means that malicious scripts could be executed every time banners are displayed, creating ongoing exposure for all users interacting with the platform.
Security professionals should recognize this vulnerability as a direct violation of CWE-79, which specifically addresses cross-site scripting flaws in web applications. The attack patterns align with ATT&CK technique T1566, focusing on the initial access phase through malicious web content delivery. Organizations should prioritize immediate remediation by upgrading to phpAdsNew and phpPgAds versions 2.0.8 or later, which contain proper input validation and output encoding mechanisms. Additionally, implementing proper content security policies, input sanitization routines, and regular security assessments can help prevent similar vulnerabilities in other web applications. The remediation process should also include comprehensive testing to ensure that all user-supplied parameters are properly validated before being processed or displayed in web responses, establishing a robust defense-in-depth strategy against persistent XSS threats.
