CVE-2010-2758 in Bugzilla
Summary
by MITRE
Bugzilla 2.17.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2 generates different error messages depending on whether a product exists, which makes it easier for remote attackers to guess product names via unspecified use of the (1) Reports or (2) Duplicates page.

CVE-2010-2758 represents a information disclosure vulnerability affecting multiple versions of the Bugzilla bug tracking system. This flaw manifests through inconsistent error messaging mechanisms that reveal whether specific product names exist within the system. The vulnerability exists in Bugzilla versions ranging from 2.17.1 through 3.2.7, 3.3.1 through 3.4.7, 3.5.1 through 3.6.1, and 3.7 through 3.7.2, creating a significant security risk for organizations relying on this platform for software defect tracking and management.
The technical implementation of this vulnerability stems from the application's response handling mechanism on the Reports and Duplicates pages. When a user attempts to access these pages with non-existent product identifiers, the system generates distinct error messages compared to when valid product names are used. This differential response allows attackers to perform product name enumeration by observing the varying error messages returned by the application. The flaw operates at the application logic level, where the system fails to maintain consistent error handling for both valid and invalid product name inputs, creating a side-channel information leak that violates the principle of least privilege and information hiding.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables attackers to systematically discover valid product names within the Bugzilla instance. This reconnaissance capability significantly reduces the difficulty of subsequent attacks, as attackers can use the discovered product names to craft more targeted exploitation attempts. The vulnerability is particularly concerning in multi-product environments where the enumeration of valid products can reveal organizational structure, development projects, and potentially sensitive information about the software development lifecycle. According to CWE-200, this represents an information disclosure weakness that can be leveraged to bypass other security controls, making it a critical vulnerability in the ATT&CK framework under the reconnaissance phase.
The attack vector for CVE-2010-2758 is straightforward and remote, requiring no authentication to exploit. Attackers can systematically submit product names to the Reports and Duplicates pages and analyze the error responses to determine which products exist within the system. This enumeration process can be automated and repeated across multiple Bugzilla instances, making it a scalable reconnaissance tool. Organizations should implement proper error handling that provides consistent responses regardless of whether product names exist, ensuring that error messages do not inadvertently reveal system information. The vulnerability highlights the importance of defensive programming practices and proper input validation, as outlined in OWASP Top 10 and NIST cybersecurity frameworks, where inconsistent error responses can provide attackers with valuable intelligence for planning more sophisticated attacks against the system.
