CVE-2018-25274 in InfraRecorder
Summary
by MITRE • 04/27/2026
InfraRecorder 0.53 contains a denial of service vulnerability that allows local attackers to crash the application by importing a maliciously crafted text file. Attackers can create a text file containing 6000 bytes of data and import it through the Edit menu's Import function to trigger an application crash.

The vulnerability in InfraRecorder 0.53 represents a classic denial of service condition that stems from inadequate input validation and memory handling within the application's text import functionality. This weakness allows local attackers to deliberately crash the application by exploiting a buffer overflow or memory corruption issue that occurs when processing large text files through the Edit menu's Import function. The specific trigger involves creating a text file containing exactly 6000 bytes of data, which when imported activates an unhandled exception that terminates the application process. This vulnerability falls under the category of improper input validation as defined by CWE-20, where the application fails to properly validate the size and content of user-supplied data before processing it. The attack vector is particularly concerning because it requires minimal technical expertise to execute, making it accessible to attackers with basic knowledge of file manipulation. The local privilege requirement means that the attacker must already have access to the target system, but this limitation does not mitigate the risk since local attackers often have significant access rights and can leverage this vulnerability as part of a broader attack strategy. The operational impact extends beyond simple application disruption, as this vulnerability could be used as a stepping stone for more sophisticated attacks or could be combined with other exploits to create a more comprehensive compromise. The vulnerability demonstrates poor memory management practices and lacks proper bounds checking mechanisms that should be implemented when handling user-provided input data. From an attacker perspective, this vulnerability aligns with ATT&CK technique T1499.004 which involves network denial of service attacks, though in this case the attack is local rather than network-based. The specific memory handling issue suggests that the application may be using fixed-size buffers or stack-based allocations that do not account for the possibility of large input data, leading to stack corruption or heap overflow conditions. This type of vulnerability is particularly dangerous in environments where InfraRecorder is used for critical operations such as optical disc burning or media management, as the application crash could result in data loss or system instability. The vulnerability also indicates a lack of proper error handling and recovery mechanisms within the application's import subsystem, which should include input size validation, memory allocation checks, and graceful degradation when encountering unexpected data sizes. The 6000-byte threshold suggests that the application has specific buffer size limitations that are not properly enforced, potentially indicating a design flaw in the text processing pipeline. The attack scenario is straightforward and reliable, making it an attractive target for malicious actors seeking to disrupt system operations or create conditions for more complex exploitation attempts. Security practitioners should note that this vulnerability is particularly relevant in environments where local privilege escalation is possible, as attackers could use this DoS condition to create persistent access points or to disrupt services that depend on the application's stability. The vulnerability also highlights the importance of implementing proper input sanitization and memory safety practices in all application components, regardless of their perceived complexity or security criticality. Organizations using InfraRecorder 0.53 should consider immediate mitigation strategies including application whitelisting, access controls, and system hardening measures to reduce the attack surface. The vulnerability serves as a reminder of the critical importance of input validation and proper memory management in preventing both denial of service conditions and potential privilege escalation scenarios that could lead to more serious security breaches.
