CVE-2022-44790 is a high-severity SQL Injection vulnerability affecting Interspire Email Marketer versions up to 6.5.1, specifically within the surveys module. This vulnerability allows an unauthenticated attacker to inject malicious SQL queries by manipulating the survey ID parameter. Because the vulnerability does not require any authentication or user interaction, it can be exploited remotely over the network. The core issue stems from improper sanitization or validation of input parameters in the surveys module, enabling attackers to craft SQL statements that the backend database executes. Successful exploitation can lead to unauthorized extraction of sensitive information stored in the database, such as user data, email lists, or campaign details. The CVSS 3.1 base score is 7.5, reflecting a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no impact on integrity or availability (I:N/A:N). There are no known public exploits in the wild at the time of publication, and no official patches or vendor advisories have been linked. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), a common and critical web application security flaw. Given the nature of Interspire Email Marketer as a marketing automation and email campaign management platform, the exposure of database contents could lead to significant privacy breaches and data leakage, especially of marketing contacts and campaign data.

For European organizations, the impact of this vulnerability can be substantial due to the sensitive nature of data managed by Interspire Email Marketer, including personal data of customers and prospects. Unauthorized data extraction could violate GDPR regulations, leading to legal penalties and reputational damage. The confidentiality breach could expose email lists, contact details, and potentially other personal identifiers, increasing risks of phishing, spam campaigns, or identity theft. Since the vulnerability does not affect integrity or availability, direct disruption of services is unlikely; however, the loss of confidentiality alone is critical. Organizations relying on Interspire Email Marketer for customer engagement, especially in sectors like retail, finance, and healthcare, may face heightened risks. Additionally, the unauthenticated nature of the exploit means attackers can scan and target vulnerable instances en masse, increasing the likelihood of widespread compromise. The absence of known exploits currently provides a window for proactive mitigation, but the ease of exploitation and public knowledge of the vulnerability suggest attackers may develop exploits soon.

European organizations should immediately audit their use of Interspire Email Marketer to identify affected versions, particularly those up to 6.5.1. Since no official patches are currently linked, organizations should implement compensating controls such as: 1) Restricting external access to the surveys module via network segmentation or firewall rules, limiting exposure to trusted IP addresses only. 2) Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the survey ID parameter. 3) Conducting thorough input validation and sanitization at the application layer if custom modifications are possible. 4) Monitoring logs for unusual query patterns or repeated access attempts to the surveys module. 5) Considering temporary disabling or removal of the surveys module if feasible until a patch is available. 6) Engaging with Interspire support or community forums to track patch releases or mitigations. 7) Preparing incident response plans for potential data breaches involving marketing data. These measures go beyond generic advice by focusing on network-level restrictions, active detection, and module-specific controls tailored to the vulnerability context.
