CVE-2015-6358 Vulnerability Summary

CVE-2015-6358: Multiple Cisco embedded devices use hardcoded X.509 certificates and SSH host keys embedded in the firmware, which allows remote attackers to defeat cryptographic protection mechanisms and conduct man-in-the-middle attacks by leveraging knowledge of these certificates and keys from another installation, aka Bug IDs CSCuw46610, CSCuw46620, CSCuw46637, CSCuw46654, CSCuw46665, CSCuw46672, CSCuw46677, CSCuw46682, CSCuw46705, CSCuw46716, CSCuw46979, CSCuw47005, CSCuw47028, CSCuw47040, CSCuw47048, CSCuw47061, CSCuw90860, CSCuw90869, CSCuw90875, CSCuw90881, CSCuw90899, and CSCuw90913.

Assessing the Risk of CVE-2015-6358

Access Complexity Graph

The exploitability of CVE-2015-6358 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2015-6358

CVE-2015-6358 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2015-6358, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2015-6358, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: High
    Exploiting CVE-2015-6358 can result in unauthorized access to sensitive data, severely compromising data privacy.
  • Integrity: None
    CVE-2015-6358 poses no threat to data integrity.
  • Availability: None
    CVE-2015-6358 does not impact system availability.

Exploit Prediction Scoring System (EPSS)

The EPSS score estimates the probability that this vulnerability will be exploited in the near future.

EPSS Score: 0.329% (probability of exploit)

EPSS Percentile: 71.17% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 28.83% of others.

CWE Common Weakness Enumeration

CWE-295

CAPEC Common Attack Pattern Enumeration and Classification

  • Creating a Rogue Certification Authority Certificate CAPEC-459 An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
  • Signature Spoofing by Improper Validation CAPEC-475 An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
