Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures (CVE) program has recently identified a significant vulnerability in Animate versions 24.0.8, 23.0.11 and earlier. This vulnerability, classified as CVE-2025-43555, is an Integer Underflow (Wrap or Wraparound) that could potentially allow an attacker to execute arbitrary code in the context of the current user. The severity of this vulnerability is compounded by the fact that its exploitation could lead<\/a> to system compromise or data leakage, making it a critical issue for all users of the affected Animate versions. This article aims to provide detailed insight into this vulnerability<\/a>, its potential impact, and how users can mitigate the potential risks.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-43555
\nSeverity: High (7.8 CVSS score)
\nAttack Vector: Local
\nPrivileges Required: None
\nUser Interaction: Required
\nImpact: Arbitrary code execution<\/a>, potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Animate | 24.0.8 and earlier versions<\/a>
\nAnimate | 23.0.11 and earlier versions<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The Integer Underflow vulnerability occurs when an integer used in the software\u2019s<\/a> operation is decremented below its minimum value, causing it to wrap around to its maximum value. In this case, a malicious actor could craft a file that, when opened by a victim, triggers the underflow and allows the execution of arbitrary code<\/a> in the context of the current user. This could potentially give the attacker the same rights as the current user, leading to system<\/a> compromise or data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following is a conceptual example of how a malicious file might be crafted to exploit the vulnerability<\/a>. Please note that this is a simplified example and real-world exploits may be more complex.<\/p>\n

# integer underflow exploit\n# arbitrary function that triggers underflow\ndef trigger_underflow(input):\nminimum_value = 0\nunderflow_value = input - 1\nif underflow_value < minimum_value:\nunderflow_value = MAX_INT\nreturn underflow_value\n# crafted file with malicious payload\nwith open('malicious_file', 'w') as f:\nf.write('malicious_payload: ' + str(trigger_underflow(0)))<\/code><\/pre>\n
As shown in the above pseudocode, the attacker writes a malicious payload to a file, which when opened, triggers an integer underflow, potentially leading to arbitrary<\/a> code execution.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users affected by this vulnerability<\/a> should apply the vendor patch as soon as it's available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. It is also advisable to avoid opening files from untrusted sources<\/a>. Regularly updating software and maintaining a robust cybersecurity posture is critical to mitigating such vulnerabilities<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
