Technical Analysis

CVE-2024-22956 is a heap-use-after-free vulnerability identified in swftools version 0.9.2, specifically within the function removeFromTo located in the source file swftools/src/swfc.c at line 838. A heap-use-after-free vulnerability occurs when a program continues to use a pointer to memory after it has been freed, leading to undefined behavior such as memory corruption, crashes, or potential arbitrary code execution. In this case, the vulnerability allows an attacker to exploit the improper handling of heap memory, which can result in high impact on confidentiality, integrity, and availability of the affected system. The CVSS 3.1 base score for this vulnerability is 7.8, indicating a high severity level. The vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H reveals that the attack vector is local (AV:L), requiring low attack complexity (AC:L), no privileges (PR:N), but user interaction is required (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no known exploits are currently in the wild, the vulnerability poses a significant risk due to the potential for arbitrary code execution or system compromise if exploited. Swftools is a collection of utilities for working with Adobe Flash files (SWF), often used in multimedia processing or legacy content management systems. The lack of vendor or product information and absence of patch links suggests that remediation may require manual code review or updates from the community or maintainers. The vulnerability is classified under CWE-416, which corresponds to use-after-free errors, a common and dangerous class of memory corruption bugs.

Potential Impact

For European organizations, the impact of CVE-2024-22956 depends largely on the extent to which swftools is used within their IT environments. Organizations involved in multimedia processing, legacy Flash content management, or digital archiving may be at risk. Exploitation of this vulnerability could lead to unauthorized code execution, data breaches, or denial of service conditions, potentially compromising sensitive information or disrupting critical services. Given the high confidentiality, integrity, and availability impacts, attackers could leverage this flaw to gain footholds within networks, escalate privileges, or disrupt operations. Although the attack vector is local and requires user interaction, insider threats or social engineering could facilitate exploitation. The absence of known exploits in the wild currently reduces immediate risk, but the high severity score and the nature of the vulnerability warrant proactive mitigation. European organizations with compliance requirements around data protection (e.g., GDPR) must consider the risk of data leakage or service disruption resulting from this vulnerability.

Mitigation Recommendations

To mitigate CVE-2024-22956, European organizations should first identify any use of swftools 0.9.2 or related versions within their infrastructure. Since no official patches are currently linked, organizations should monitor for updates from the swftools maintainers or community. In the interim, consider the following specific actions: 1) Restrict access to systems running swftools to trusted users only, minimizing the risk of local exploitation. 2) Implement strict user privilege management to reduce the impact of potential exploitation, ensuring users have only necessary permissions. 3) Employ application whitelisting and behavior monitoring to detect anomalous activity related to swftools processes. 4) If feasible, replace or phase out swftools in favor of more secure or actively maintained alternatives for Flash file processing. 5) Conduct code audits or static analysis on the swftools source code if custom builds are used, to identify and remediate use-after-free patterns. 6) Educate users about the risks of interacting with untrusted Flash content or files processed by swftools to reduce the likelihood of triggering the vulnerability. 7) Maintain up-to-date backups and incident response plans to quickly recover from potential exploitation.
