CVE-2025-61595 in mantrachain
Summary
by MITRE • 10/02/2025
MANTRA is a purpose-built RWA Layer 1 Blockchain, capable of adherence to real world regulatory requirements. Versions 4.0.1 and below do not enforce the tx gas limit in its send hooks. Send hooks can spend more gas than what remains in tx, combined with recursive calls in the wasm contract, potentially amplifying the gas consumption exponentially. This is fixed in version 4.0.2.

CVE-2025-61595 represents a critical gas limit enforcement vulnerability within the MANTRA blockchain's RWA Layer 1 infrastructure affecting versions 4.0.1 and earlier. This vulnerability stems from the absence of proper gas limit validation within the send hooks mechanism, creating a fundamental flaw in the transaction processing pipeline that directly violates core blockchain security principles. The issue manifests when send hooks execute without proper gas consumption boundaries, allowing malicious actors to exploit the system's gas accounting mechanisms through recursive wasm contract calls.
The technical exploitation of this vulnerability leverages the recursive call pattern within wasm contracts to exponentially amplify gas consumption beyond the allocated transaction limits. This creates a potential denial of service scenario where a single transaction can consume excessive computational resources, effectively grinding the network to a halt. The flaw aligns with CWE-1321 which specifically addresses improper enforcement of computational resource limits, and represents a direct violation of the gas metering principles that form the foundation of blockchain consensus mechanisms. The vulnerability creates an environment where malicious actors can perform gas exhaustion attacks, potentially causing network-wide disruptions while maintaining compliance with regulatory requirements that the blockchain was designed to support.
The operational impact of this vulnerability extends beyond simple network degradation to encompass potential financial losses and system instability within the RWA ecosystem. Attackers can construct transactions that consume disproportionate amounts of computational resources, leading to transaction processing delays, increased node operational costs, and potential network partitioning. This vulnerability particularly threatens the regulatory compliance aspects that MANTRA was designed to support, as network instability could compromise the integrity of real-world asset tracking and compliance reporting mechanisms. The exponential gas consumption amplification through recursive calls creates a particularly dangerous scenario where a single malicious transaction can cascade into system-wide performance degradation, making it a high-priority security concern for any blockchain infrastructure supporting real-world asset integration.
Mitigation strategies for CVE-2025-61595 require immediate deployment of version 4.0.2 which implements proper gas limit enforcement in send hooks. Network operators must also implement additional monitoring mechanisms to detect anomalous gas consumption patterns and establish automated alerts for transactions exceeding predefined gas thresholds. The fix addresses the root cause by ensuring that send hooks properly respect transaction gas limits and implement recursive call depth limiting within wasm contracts. Organizations should conduct thorough testing of their smart contract deployments to ensure compatibility with the new gas enforcement mechanisms. This vulnerability demonstrates the critical importance of proper resource management in blockchain systems and aligns with ATT&CK technique T1499.004 which covers network denial of service attacks through resource exhaustion, emphasizing that such vulnerabilities can be exploited to compromise the availability and integrity of blockchain networks while undermining the trustless properties that make these systems valuable for real-world applications.
