CVE-2019-25604: DVDXPlayer Pro Buffer Overflow Vulnerability

CVE-2019-25604 Overview

CVE-2019-25604 is a local buffer overflow vulnerability in DVD-X Player Pro 5.5 that abuses Structured Exception Handling (SEH) to achieve arbitrary code execution. The flaw is triggered when the application parses a malicious playlist (.plf) file. An attacker who convinces a user to open a crafted playlist can overflow a fixed-size buffer, overwrite the SEH chain, and redirect execution into attacker-supplied shellcode. The vulnerability is categorized as an out-of-bounds write [CWE-787] and carries a CVSS 4.0 score of 8.6.

Critical Impact
Successful exploitation grants arbitrary code execution under the privileges of the user running DVD-X Player Pro, enabling local compromise of the host.

Affected Products

DVD-X Player Pro 5.5
Playlist file parser (.plf) component
Windows installations of DVD-X Player Pro

Technical Details for CVE-2019-25604

Vulnerability Analysis

The vulnerability resides in the routine that processes playlist (.plf) files in DVD-X Player Pro 5.5. The parser copies playlist contents into a fixed-size stack buffer without validating the input length. When the supplied data exceeds the buffer size, adjacent stack memory is overwritten, including the SEH record stored on the stack frame.

Because the parser uses Structured Exception Handling, an attacker can craft input that overwrites the Next SEH pointer and the SEH handler address. Triggering an exception after the overflow causes Windows to dispatch the corrupted handler, transferring execution to attacker-controlled memory.

The issue is classified under [CWE-787] Out-of-bounds Write, the underlying weakness for classic stack buffer overflows.

Root Cause

The root cause is the absence of bounds checking when reading playlist data into a stack buffer. The application trusts the length of strings inside the .plf file and performs an unchecked copy operation. Compiler and linker protections such as /SAFESEH and /GS are either absent or insufficient for the affected module, allowing the SEH overwrite technique to succeed.

Attack Vector

Exploitation requires local user interaction. An attacker delivers a malicious .plf file by email, removable media, or a download. When the victim opens the file in DVD-X Player Pro 5.5, the parser triggers the overflow.

A typical exploit layout places a NOP sled and shellcode in the buffer, followed by a short jump in the Next SEH field and a POP POP RET gadget address in the SEH handler slot. When the exception fires, execution pivots to the attacker-controlled shellcode. Public proof-of-concept code is available in Exploit-DB #46962 and the VulnCheck Advisory for DVD-X Player.

No verified code example is reproduced here. Refer to the published advisories for the technical proof-of-concept structure.

Detection Methods for CVE-2019-25604

Indicators of Compromise

Unexpected .plf files staged in user download directories, temporary folders, or removable media
DVD-X Player process (PlayerPro.exe) crashing with access violations referencing addresses outside loaded modules
DVD-X Player spawning child processes such as cmd.exe, powershell.exe, or rundll32.exe
Outbound network connections initiated by the DVD-X Player process to untrusted hosts

Detection Strategies

Inspect .plf files for oversized string fields and embedded shellcode patterns such as long NOP sleds (\\x90\\x90...) or known egg-hunter signatures
Monitor for process crash telemetry where the faulting module belongs to DVD-X Player and the exception involves SEH chain corruption
Correlate execution of DVD-X Player with anomalous child process creation using EDR behavioral analytics

Monitoring Recommendations

Enable Windows Error Reporting and forward crash dumps for review when DVD-X Player terminates unexpectedly
Alert on file write events that drop .plf files from email clients, browsers, or USB devices
Track command-line arguments passed to DVD-X Player to flag execution against unusual playlist paths

How to Mitigate CVE-2019-25604

Immediate Actions Required

Uninstall or disable DVD-X Player Pro 5.5 on managed endpoints until a vendor fix is confirmed
Block opening of .plf files received from untrusted sources at the email gateway and web proxy
Restrict execution of DVD-X Player to a minimal user population that has a clear business need

Patch Information

No vendor-supplied patch is referenced in the public advisories for CVE-2019-25604. Consult the DVD-X Player Download Page for the latest available build and validate whether the playlist parser has been remediated before redeployment. If no fixed version is available, treat the product as end-of-life for security purposes and replace it.

Workarounds

Remove the file association for .plf so the file type does not auto-launch DVD-X Player
Enforce application control policies (for example, Windows Defender Application Control or AppLocker) that block DVD-X Player Pro 5.5 from executing
Enable system-wide exploit mitigations such as Data Execution Prevention (DEP) and mandatory Address Space Layout Randomization (ASLR) via Exploit Protection settings

bash

# Configuration example: block .plf execution and enforce exploit mitigations on Windows

# Remove file association for .plf
cmd.exe /c "assoc .plf="

# Enable mandatory ASLR and DEP system-wide via PowerShell
Set-ProcessMitigation -System -Enable DEP,ForceRelocateImages,BottomUp,HighEntropy

# AppLocker publisher rule example to deny DVD-X Player Pro 5.5
