CVE-2019-25552 in CEWE PHOTO SHOW
Summary
by MITRE • 03/21/2026
CEWE PHOTO SHOW 6.4.3 contains a denial of service vulnerability that allows attackers to crash the application by submitting an excessively long buffer to the password field. Attackers can paste a large string of repeated characters into the password input during the upload process to trigger an application crash.

The vulnerability identified as CVE-2019-25552 affects CEWE PHOTO SHOW version 6.4.3 and represents a classic denial of service condition stemming from inadequate input validation within the application's password handling mechanism. This flaw exists in the software's upload process where the application fails to properly sanitize or limit the length of data submitted to the password field, creating an exploitable condition that can be leveraged by malicious actors to disrupt normal application operations.
The technical implementation of this vulnerability demonstrates a buffer overflow condition that occurs when the application attempts to process an excessively long string of repeated characters within the password input field. This type of vulnerability falls under the CWE-122 category of buffer overflow conditions, specifically representing a situation where the application does not properly validate input length before attempting to process the data. The flaw occurs during the upload process when the software attempts to store or validate the password input without implementing proper bounds checking or length limitations, leading to memory corruption that ultimately results in application termination.
From an operational perspective, this vulnerability presents a significant risk to users of CEWE PHOTO SHOW as it allows remote attackers to induce system instability through simple text manipulation. The attack vector is particularly concerning because it requires minimal technical expertise to execute, as attackers only need to paste a large string of repeated characters into the password field. This makes the vulnerability accessible to attackers of varying skill levels and increases the potential for widespread impact. The denial of service condition effectively prevents legitimate users from completing their intended upload operations, creating operational disruption and potentially impacting business processes that depend on the application's availability.
The vulnerability aligns with ATT&CK technique T1499.004 which covers "Utilities: Endpoint Denial of Service" and demonstrates how application-level flaws can be exploited to create service disruption. Organizations using CEWE PHOTO SHOW should consider implementing input validation controls at the application boundary to prevent such conditions from occurring. The recommended mitigations include implementing strict input length limits for password fields, incorporating proper bounds checking mechanisms, and establishing input sanitization routines that can detect and reject excessively long strings before they reach critical processing components. Additionally, application developers should implement robust error handling procedures that can gracefully manage malformed input without causing application termination. This vulnerability underscores the importance of defensive programming practices and input validation as fundamental security controls that should be implemented throughout application development lifecycle to prevent similar conditions from occurring in other software components.
