Technical Analysis
The SLE API for Java, an implementation of CCSDS Space Link Extension Services, contains a vulnerability in versions before 5.1.7 where the ISP1 PDU handling path decodes an attacker-controlled body length and allocates a byte array without an upper bound. Malformed or truncated input can cause unexpected termination of reads, allowing an unauthenticated client to trigger exceptions, resource leakage, and denial of service conditions. This vulnerability is tracked as CWE-770 (Allocation of Resources Without Limits or Throttling). The issue is resolved in version 5.1.7.
Potential Impact
An unauthenticated attacker can send specially crafted input to the SLE listening service, causing the application to allocate excessive memory without limits. This can lead to resource exhaustion, exceptions, and denial of service, impacting availability. There is no impact on confidentiality or integrity according to the CVSS vector.
Mitigation Recommendations
Upgrade to version 5.1.7 or later, where the vulnerability is fixed. No other mitigation or temporary workaround is indicated.
