Rhonabwy before v1.1.5 was discovered to contain a buffer overflow via the component r_jwe_aesgcm_key_unwrap. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted JWE token.
AnalysisAI
Rhonabwy before v1.1.5 was discovered to contain a buffer overflow via the component r_jwe_aesgcm_key_unwrap. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. Rhonabwy before v1.1.5 was discovered to contain a buffer overflow via the component r_jwe_aesgcm_key_unwrap. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted JWE token. Affected products include: Rhonabwy Project Rhonabwy.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
In Rhonabwy through 1.1.13, HMAC signature verification uses a strcmp function that is vulnerable to side-channel attack
Rhonabwy 0.9.99 through 1.1.x before 1.1.7 doesn't check the RSA private key length before RSA-OAEP decryption. Rated hi
