Ghidra vulnerabilities

Ghidra versions 9.2 through 12.1.4 contain a heap out-of-bounds read vulnerability in StringManager::getCodepoint when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters without validating remaining buffer length. Attackers can craft malicious binaries containing strings or constant byte stores that end in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output.

Ghidra versions through 12.1.4 contain a stack-based out-of-bounds write vulnerability in the decompiler's leftshift128 function when processing negative shift amounts from p-code. Attackers can craft malicious binaries with specific instruction sequences that trigger the overflow when decompiled, corrupting memory and potentially achieving code execution.

Ghidra versions through 12.1.4 contain a heap use-after-free vulnerability in the decompiler's Funcdata::opInsertAfter function caused by stale INDIRECT effect-op references. Attackers can craft a malicious binary with a specific x86-64 sequence that triggers the vulnerability during decompilation, causing the decompile helper process to crash and denying service to analysts and automated analysis pipelines.

Vulnerability in Ghidra before 12.1.4. Failure to validate TYPE_COL byte in OptionsDB.createUnregisteredOption() causes ArrayIndexOutOfBoundsException that leaves domain objects permanently locked. Malicious database file can cause application stall and prevent resource cleanup.

Ghidra before 12.1.3 contains an uncontrolled resource consumption vulnerability in the PDB parser that allows attackers to terminate the Ghidra process by supplying a crafted PDB file with an oversized parameters section. The AbstractPdb deserialization routine reads all remaining parameters into an unbounded list, causing uncontrolled heap growth that triggers an OutOfMemoryError which bypasses exception handling and crashes the application.

Ghidra contains an arbitrary code execution vulnerability in the Swift demangler analyzer that allows an attacker to execute arbitrary binaries by supplying a malicious Ghidra project with a crafted Swift tool directory path. When a victim opens the attacker-supplied project, SwiftDemanglerAnalyzer restores the persisted Swift binary directory from project state and SwiftNativeDemangler executes the resolved binary without integrity or signature verification, causing attacker-controlled executables to run under the Ghidra process user with no prompt or confirmation.

Ghidra before 12.1.1 contains an uncontrolled memory allocation vulnerability in the Mach-O binary parser that allows attackers to cause denial of service. An attacker can supply a crafted Mach-O binary with an arbitrarily large ncmds load command count value, forcing the parser to allocate excessive heap memory without validating file size, crashing the Ghidra JVM.

Ghidra before version 12.1 contains a SQL injection vulnerability in BSim filter types that concatenate user-supplied values directly into SQL queries without escaping or parameterization. Remote attackers can inject arbitrary SQL via the BSim network query protocol to read, modify, or delete data in the PostgreSQL database.

Ghidra before version 12.1 contains a heap-use-after-free vulnerability in the decompiler's HighVariable::merge() function during the variable merging pass. Attackers can trigger this vulnerability by crafting a binary that causes stale pointers in the HighIntersectTest::highedgemap cache to be dereferenced, reading and writing the flags field of freed heap memory when a user opens the binary in Ghidra's decompiler view.

Ghidra before version 12.2 contains an unauthenticated path traversal vulnerability in the IsfServer that accepts TCP connections and passes client-supplied namespace strings directly to filesystem operations without validation. Remote attackers can connect to port 54321 and send crafted protobuf messages with traversal sequences to enumerate filesystem paths and probe arbitrary files.

Ghidra before version 12.0.4 contains a path traversal vulnerability in the theme import functionality, allowing attackers to write files outside the intended theme directory. Attackers can craft malicious theme ZIP files with traversal sequences in filenames to execute arbitrary code or modify sensitive files like .bashrc or .ssh/authorized_keys.

Ghidra before version 12.1 contains an authentication bypass vulnerability in PKIAuthenticationModule.authenticate() that allows any user with a valid CA-signed certificate to impersonate other users by presenting their public certificate with a null signature.

Ghidra before version 12.0.3 contains an out-of-memory vulnerability in the rust_demangle function that allocates unbounded output buffers without size limits. Attackers can craft malicious Rust symbol names in binaries to trigger exponential memory allocation, causing process crashes during binary analysis.

Ghidra before version 12.0.2 contains a path traversal vulnerability in the extension installer that fails to validate ZIP entry names during extraction. Attackers can craft malicious extensions with traversal sequences like ../ in filenames to write arbitrary files outside the intended directory, enabling code execution.

Ghidra before version 12.1 contains an unsafe deserialization vulnerability in client-side Shared-Project RMI connection code that allows unauthenticated remote code execution. Attackers can craft a malicious project file with a ghidra:// URL that, when opened via File → Open Project, deserializes untrusted objects using a Jython 2.7.4 gadget chain to execute arbitrary commands.

Ghidra before version 12.1 contains a command injection vulnerability in URL annotation handling on Windows where cmd.exe metacharacters are not properly escaped. Attackers can execute arbitrary commands under the Ghidra user's privileges by embedding malicious URLs in program comments that victims click.

Ghidra versions 11.0 through 12.0 contain a SQL injection vulnerability in the changePassword() method of PostgresFunctionDatabase. The failure to escape double quotes in usernames interpolated into ALTER ROLE statements allows authenticated attackers to inject SQL commands via crafted username parameters in PasswordChange network messages.

A path traversal vulnerability in Ghidra before version 12.1 in the SameDirDebugInfoProvider component allows attackers to inject traversal sequences into file paths. By crafting malicious ELF binaries with a .gnu_debuglink section, it is possible to probe filesystem existence and leak CRC32 hashes of arbitrary files during automatic DWARF analysis.

A heap-use-after-free vulnerability in the SLEIGH library before version 12.1 (Ghidra) exists in SleighBuilder::generatePointerAdd due to iterator invalidation when PcodeCacher::allocateInstruction reallocates the issued vector.

Ghidra versions 10.2 through 12.0 contain an uncontrolled resource consumption vulnerability in ExportTrie.parseTrie() lacking cycle detection when processing Mach-O export tries. A crafted Mach-O binary with circular references causes unbounded queue growth and exponential string concatenation, leading to OutOfMemoryError and JVM crash.

Ghidra before version 11.2 contains a use-after-free vulnerability in the Sleigh backend caused by undefined static initialization order of the SleighArchitecture::translators and XmlArchitectureCapability singletons. Attackers can trigger an infinite loop or denial of service during shutdown by exploiting the unsafe destruction order that causes iteration over deallocated memory.
