CVE-2025-55298

CVE-2025-55298 is a high-severity security vulnerability in Magick.NET-Q16-AnyCPU (nuget), affecting versions < 14.8.1. It is fixed in 14.8.1.

Summary

A format string bug vulnerability exists in InterpretImageFilename function where user input is directly passed to FormatLocaleString without proper sanitization. An attacker can overwrite arbitrary memory regions, enabling a wide range of attacks from heap overflow to remote code execution.

Details

root cause

MagickExport size_t InterpretImageFilename(const ImageInfo *image_info,
  Image *image,const char *format,int value,char *filename,
  ExceptionInfo *exception)
{

...

  while ((cursor=strchr(cursor,'%')) != (const char *) NULL)
  {
    const char
      *q = cursor;

    ssize_t
      offset = (ssize_t) (cursor-format);

    cursor++;  /* move past '%' */
    if (*cursor == '%')
      {
        /*
          Escaped %%.
        */
        cursor++;
        continue;
      }
    /*
      Skip padding digits like %03d.
    */
    if (isdigit((int) ((unsigned char) *cursor)) != 0)
      (void) strtol(cursor,(char **) &cursor,10);
    switch (*cursor)
    {
      case 'd':
      case 'o':
      case 'x':
      {
        ssize_t
          count;

        count=FormatLocaleString(pattern,sizeof(pattern),q,value);
        if ((count <= 0) || (count >= MagickPathExtent) ||
            ((offset+count) >= MagickPathExtent))
          return(0);
        (void) CopyMagickString(p+offset,pattern,(size_t) (MagickPathExtent-
          offset));
        cursor++;
        break;
      }

When the InterpretImageFilename function processes a filename beginning with format specifiers such as %d, %o, or %x, the filename string is directly passed as a parameter to the FormatLocaleString function.

MagickExport ssize_t FormatLocaleString(char *magick_restrict string,
  const size_t length,const char *magick_restrict format,...)
{
  ssize_t
    n;

  va_list
    operands;

  va_start(operands,format);
  n=FormatLocaleStringList(string,length,format,operands);
  va_end(operands);
  return(n);
}

MagickPrivate ssize_t FormatLocaleStringList(char *magick_restrict string,
  const size_t length,const char *magick_restrict format,va_list operands)
{
...
n=(ssize_t) _vsnprintf_l(string,length,format,locale,operands);

Inside FormatLocaleString, the variable argument list is initialized through va_start, after which the format string processing occurs by interpreting the format specifiers and using corresponding values from CPU registers and the call stack as arguments for the formatting operations.

==55653==ABORTING

Processing a malicious filename containing format string specifiers such as %d%n results in corruption of the SplayTree structure stored in the r8 register. The corrupted structure contains invalid pointer values that are later dereferenced by the SplaySplayTree function, causing the function to access unintended memory locations and triggering a heap overflow condition.

The exploit achieves remote code execution by leveraging format string vulnerabilities to perform a write-what-where attack. The payload systematically overwrites return addresses on the stack, redirecting program execution to a one-gadget ROP chain that spawns a shell with the current process privileges.

Exploitation Process:

  1. Format string payload corrupts stack pointers through positional parameters
  2. Multiple 2-byte writes (%hn) progressively overwrite the return address
  3. Final payload redirects execution to a one-gadget (0x00007ffff66ebc85)
  4. One-gadget executes /bin/sh with inherited process permissions

Remote Exploitation Feasibility:
While this PoC demonstrates local shell execution with ASLR disabled, remote code execution is achievable in real-world scenarios through brute force attacks. When stack layout conditions are favorable, attackers can perform 1.5-byte return address brute force and 1.5-byte libc base address brute force to gain shell access.

Important: The numeric parameters within the format string payload are environment-dependent and may require modification for different target systems due to variations in memory layout and stack structure.

Note: This demonstrates complete system compromise, as the attacker gains interactive shell access to the target system.

Additional notes from the ImageMagick team:

On many modern toolchains and OSes, format‑string exploits using %n are already mitigated or blocked by default (e.g., -Wformat-security, _FORTIFY_SOURCE, hardened libc behavior, ASLR/stack canaries). That can make exploitation impractical in typical builds so you might not be vulnerable but it would still be wise to upgrade to the most recent version. We also already provide the following mitigation:

To prevent unintended interpretation of the filename as a format string, users can explicitly disable format string parsing by defining the filename as a literal. This can be done using the following directive:

  • In wrappers: filename:literal
  • From the command line: -define filename:literal=true

Impact

This format string vulnerability enables attackers to achieve complete system compromise through arbitrary memory read/write operations and remote code execution. Attackers can access sensitive data stored in process memory, overwrite critical system structures, and execute arbitrary code with ImageMagick's privileges.

The vulnerability is particularly dangerous in web applications processing user-uploaded images and automated image processing systems. Successful exploitation can lead to privilege escalation, data exfiltration, and lateral movement within compromised networks.

CVE-2025-55298 has a CVSS score of 7.5 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (14.8.1); upgrading removes the vulnerable code path.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Remediation advice

Two potential mitigation approaches:

  1. Input Validation: Add format string validation in InterpretImageFilename to reject filenames containing format specifiers (%n, %s, %x, etc.) before passing to FormatLocaleString
  2. Safe Parsing: Modify the format string processing to parse and validate each format specifier individually rather than passing the entire user-controlled string directly to FormatLocaleString

Frequently Asked Questions

  1. What is CVE-2025-55298? CVE-2025-55298 is a high-severity security vulnerability in Magick.NET-Q16-AnyCPU (nuget), affecting versions < 14.8.1. It is fixed in 14.8.1.
  2. How severe is CVE-2025-55298? CVE-2025-55298 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

  5. Is CVE-2025-55298 exploitable, and should I be worried? Whether CVE-2025-55298 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

  6. What actually determines whether CVE-2025-55298 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
