CVE-2026-45181: CWE-88 Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in Hex-Rays IDA
Hex-Rays IDA Pro versions 9. 2 and 9. 3 prior to 9. 3sp2 contain a vulnerability where improper neutralization of argument delimiters allows an attacker to inject arguments during Clang dependency-file generation. This can enable an attacker to place malicious code into the plugins directory if a victim opens a crafted . i64 file supplied by the attacker. The vulnerability has a CVSS score of 6. 5, indicating a medium severity level. No official patch or remediation guidance is currently available from the vendor. The vulnerability requires local access with high attack complexity and user interaction, and it can lead to high confidentiality and integrity impact with low availability impact.
AI Analysis
Technical Summary
CVE-2026-45181 is an argument injection vulnerability (CWE-88) in Hex-Rays IDA Pro 9.2 and 9.3 before 9.3sp2. The issue arises because the software does not properly block Clang dependency-file generation arguments, allowing an attacker to inject malicious arguments. This can be exploited by providing a specially crafted .i64 file, which causes the victim's IDA Pro to place attacker-controlled code into the plugins directory. The vulnerability requires local access with user interaction and has a CVSS 3.1 base score of 6.5 (AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:L). No vendor advisory or patch information is currently provided.
Potential Impact
Successful exploitation can lead to an attacker placing malicious code into the plugins directory of IDA Pro, potentially compromising confidentiality and integrity of the affected system. The availability impact is low. The attack requires local access and user interaction, with high attack complexity, limiting the ease of exploitation. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should avoid opening untrusted .i64 files and restrict local access to trusted users only. Monitor vendor communications for updates regarding patches or official mitigations.
