CVE-2016-8303: Vulnerability in the Oracle FLEXCUBE Universal Banking component of Oracle Financial Services Applications (subcomponent: Core). Supported versions that are affected are 11.3.0, 11.4.0, 12.0.1, 12.0.2, 12.0.3, 12.1.0 and 12.2.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle FLEXCUBE Universal Banking. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle FLEXCUBE Universal Banking, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle FLEXCUBE Universal Banking accessible data as well as unauthorized read access to a subset of Oracle FLEXCUBE Universal Banking accessible data. CVSS v3.0 Base Score 6.1 (Confidentiality and Integrity impacts).
The exploitability of CVE-2016-8303 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-2016-8303 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-2016-8303, 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-2016-8303, 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: 0.133% (probability of exploit)
EPSS Percentile: 49.88%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 50.12% of others.
