Summary
by MITRE • 09/16/2022
Adobe InDesign versions 16.4.2 (and earlier) and 17.3 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Adobe InDesign versions 16.4.2 and earlier as well as 17.3 and earlier contain a critical out-of-bounds read vulnerability designated as CVE-2022-30675 that presents significant security implications for affected systems. This vulnerability resides within the application's memory handling mechanisms and represents a classic example of a buffer over-read condition that falls under the Common Weakness Enumeration category CWE-125. The flaw occurs when the application processes specially crafted malicious files that trigger improper bounds checking during memory access operations. When an attacker successfully exploits this vulnerability, they can read memory locations that should remain protected, potentially exposing sensitive information such as stack canaries, heap metadata, or other critical system data.
The operational impact of this vulnerability extends beyond simple information disclosure as it directly undermines fundamental security mitigations designed to protect against exploitation. Address Space Layout Randomization ASLR becomes ineffective when attackers can leverage out-of-bounds reads to discover memory layout information, effectively allowing them to bypass these critical protection mechanisms. This vulnerability aligns with techniques described in the MITRE ATT&CK framework under the T1059.001 tactic for execution and T1068 for escalation of privileges. The attack vector requires user interaction, meaning victims must willingly open a malicious file, but this social engineering requirement does not diminish the severity of the vulnerability. The exploitation process typically involves crafting a malicious document that, when opened in Adobe InDesign, triggers the out-of-bounds read condition and subsequently reveals memory contents that can be leveraged for more sophisticated attacks.
The technical implementation of this vulnerability demonstrates a failure in input validation and memory management within Adobe InDesign's document parsing subsystem. When processing malformed or maliciously constructed documents, the application fails to properly validate array indices or buffer boundaries before performing memory reads. This allows attackers to access memory regions beyond the intended buffer limits, potentially exposing sensitive data that could include cryptographic keys, authentication tokens, or other confidential information. The vulnerability's classification as a remote code execution risk increases the potential impact significantly, as it provides attackers with the capability to gather information necessary for bypassing security controls and potentially achieving full system compromise. Organizations utilizing Adobe InDesign should prioritize immediate patching of affected versions to prevent exploitation, as the vulnerability represents a substantial risk to enterprise security infrastructure and data protection mechanisms.
