CVE-2013-7030: The TFTP service in Cisco Unified Communications Manager (aka CUCM or Unified CM) allows remote attackers to obtain sensitive information from a phone via an RRQ operation, as demonstrated by discovering a cleartext UseUserCredential field in an SPDefault.cnf.xml file. NOTE: the vendor reportedly disputes the significance of this report, stating that this is an expected default behavior, and that the product's documentation describes use of the TFTP Encrypted Config option in addressing this issue
The exploitability of CVE-2013-7030 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).
With low attack complexity and no required privileges, CVE-2013-7030 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
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.
Above is the CVSS Sub-score Breakdown for CVE-2013-7030, 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.
Below is the Impact Analysis for CVE-2013-7030, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 28.291% (probability of exploit)
EPSS Percentile: 96.95%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 3.049999999999997% of others.
