Source: CVE
Vendor/Project: Digital Arts Inc.
Product: i-FILTER

Description

The optional feature 'Anti-Virus & Sandbox' of i-FILTER contains an issue with improper pattern file validation. If exploited, the product may treat an unauthorized pattern file as an authorized. If the product uses a specially crafted pattern file, information in the server where the product is running may be retrieved, and/or cause a denial of service (DoS) condition.

Technical Analysis

CVE-2025-47149 is a medium-severity vulnerability affecting the 'Anti-Virus & Sandbox' optional feature of Digital Arts Inc.'s i-FILTER product, specifically versions 10.50R01 through 10.67R02. The vulnerability arises from improper validation of pattern files used by the product. Pattern files are typically used to detect malicious content or behaviors, and in this case, the product fails to adequately verify the authenticity and integrity of these files. An attacker who crafts a specially designed pattern file could exploit this flaw to have the product accept an unauthorized pattern file as legitimate. This could lead to two primary impacts: first, unauthorized retrieval of information from the server hosting the i-FILTER product, potentially exposing sensitive data; second, the ability to cause a denial of service (DoS) condition, disrupting normal operations. The vulnerability does not require any privileges or user interaction to exploit and can be triggered remotely over the network, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). However, the impact on confidentiality is rated as none, with integrity impact being low and no impact on availability, which suggests that the DoS impact might be limited or conditional. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability highlights a weakness in the trust model of pattern file validation within i-FILTER's security mechanisms, potentially undermining the product's ability to reliably filter and sandbox malicious content.

Potential Impact

For European organizations using i-FILTER versions 10.50R01 to 10.67R02, this vulnerability could lead to unauthorized information disclosure from servers running the product, which may include sensitive corporate or personal data depending on the deployment context. The DoS potential could disrupt web filtering or security services, impacting business continuity and user productivity. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face compliance risks if sensitive information is exposed. Additionally, disruption of filtering services could increase exposure to other threats by disabling or degrading security controls. Given that exploitation does not require authentication or user interaction, attackers could remotely target vulnerable systems, increasing the risk surface. However, the medium severity and lack of known exploits suggest that immediate widespread impact may be limited but should not be underestimated, especially in high-value or critical infrastructure environments.

Mitigation Recommendations

European organizations should prioritize the following mitigations: 1) Immediate inventory and identification of all i-FILTER deployments, verifying versions to determine exposure. 2) Engage with Digital Arts Inc. for official patches or updates addressing this vulnerability; if unavailable, implement compensating controls such as restricting network access to the i-FILTER management interfaces and pattern file update mechanisms to trusted sources only. 3) Monitor network traffic and logs for unusual pattern file update attempts or anomalies indicating exploitation attempts. 4) Employ network segmentation to isolate i-FILTER servers from critical systems to limit potential impact. 5) Conduct regular backups and ensure incident response plans include scenarios for DoS and data leakage related to this vulnerability. 6) Consider deploying additional endpoint or network security controls to detect and prevent exploitation attempts targeting pattern file validation weaknesses. 7) Educate security teams about this vulnerability to ensure rapid detection and response.
