CVE-2017-17302 Vulnerability Summary

CVE-2017-17302: Huawei DP300 V500R002C00, RP200 V600R006C00, TE30 V100R001C10, V500R002C00, V600R006C00, TE40 V500R002C00, V600R006C00, TE50 V500R002C00, V600R006C00, TE60 V100R001C10, V500R002C00, V600R006C00 have a memory leak vulnerability. An authenticated, local attacker may craft and load some specific Certificate Revocation List(CRL) configuration files to the devices repeatedly. Due to not release allocated memory properly, successful exploit may result in memory leak and services abnormal.

Assessing the Risk of CVE-2017-17302

Access Complexity Graph

The exploitability of CVE-2017-17302 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-2017-17302

CVE-2017-17302 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.

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-2017-17302, 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-2017-17302, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2017-17302 has no significant impact on data confidentiality.
  • Integrity: None
    CVE-2017-17302 poses no threat to data integrity.
  • Availability: Low
    CVE-2017-17302 may slightly degrade system performance without fully affecting service availability.

Exploit Prediction Scoring System (EPSS)

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

EPSS Score: 0.042% (probability of exploit)

EPSS Percentile: 5.07% (lower percentile = lower relative risk)
This vulnerability is less risky than approximately 94.93% of others.

CWE Common Weakness Enumeration

CWE-772

CAPEC Common Attack Pattern Enumeration and Classification

  • HTTP DoS CAPEC-469 An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.
