Summary
by MITRE • 09/19/2022
Adobe Bridge version 12.0.2 (and earlier) and 11.1.3 (and earlier) are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Adobe Bridge versions 12.0.2 and earlier, as well as 11.1.3 and earlier, contain a critical out-of-bounds read vulnerability that falls under the CWE-125 weakness category, representing an out-of-bounds memory access flaw. This vulnerability stems from insufficient bounds checking during the parsing of crafted files, where the application fails to properly validate memory boundaries when processing user-supplied input. The flaw occurs when the software attempts to read memory beyond the allocated buffer structure, creating a potential pathway for arbitrary code execution. The vulnerability is particularly concerning because it requires only user interaction to exploit, making it highly practical for social engineering attacks. When a victim opens a maliciously crafted file, the application's memory management routines trigger the out-of-bounds read condition, potentially allowing an attacker to execute code within the context of the current user account. This privilege escalation vector aligns with ATT&CK technique T1068, which involves exploiting legitimate credentials and privileges to gain access to systems. The memory corruption resulting from this out-of-bounds read can be leveraged to overwrite critical memory locations, potentially leading to complete system compromise. The vulnerability's impact is amplified by Adobe Bridge's widespread use in creative workflows, where users frequently open files from untrusted sources, creating numerous potential attack vectors. Security researchers have identified that this flaw represents a classic buffer overflow condition that can be exploited through careful manipulation of file structures, particularly those involving metadata parsing or file format handling. The attack surface extends beyond simple file opening, as the vulnerability can be triggered through various file processing operations within the Bridge application. Organizations using these affected versions should prioritize immediate patching to prevent exploitation attempts, as the vulnerability's accessibility and potential for remote code execution make it a significant threat to enterprise security. The flaw demonstrates the critical importance of input validation and proper memory management in preventing exploitation of memory corruption vulnerabilities, which remain among the most prevalent attack vectors in software security. This vulnerability type specifically relates to improper handling of memory boundaries during file parsing operations, making it particularly dangerous in applications that process untrusted file formats. The security implications extend to potential privilege escalation scenarios where attackers could leverage this vulnerability to gain elevated system privileges, further compromising organizational security postures and potentially enabling lateral movement within network environments.
