An attacker able to reset this property on an existing `ConnectionPoolDataSource`, or via maliciously crafted Java-serialized objects and `javax.naming.Reference` instances, could trigger deserialization. Combined with vulnerabilities in its main dependency, mchange-commons-java, which includes code mirroring early JNDI implementations with ungated support for remote `factoryClassLocation` values, attackers could set c3p0's `userOverridesAsString` to hex-encoded serialized objects that include objects \"indirectly serialized\" via JNDI references. Deserialization of those objects and dereferencing of the embedded `javax.naming.Reference` objects could provoke the download and execution of malicious code from a remote `factoryClassLocation`, leading to arbitrary code execution on the application's `CLASSPATH`.", "category":"description", "title":"Vulnerability Description" } ], "product_status":{ "fixed":[ "openEuler-24.03-LTS-SP1:c3p0-0.9.5.4-4.oe2403sp1.noarch", "openEuler-24.03-LTS-SP1:c3p0-help-0.9.5.4-4.oe2403sp1.noarch", "openEuler-24.03-LTS-SP2:c3p0-0.9.5.4-4.oe2403sp2.noarch", "openEuler-24.03-LTS-SP2:c3p0-help-0.9.5.4-4.oe2403sp2.noarch", "openEuler-24.03-LTS-SP3:c3p0-0.9.5.4-4.oe2403sp3.noarch", "openEuler-24.03-LTS-SP3:c3p0-help-0.9.5.4-4.oe2403sp3.noarch", "openEuler-20.03-LTS-SP4:c3p0-0.9.5.4-4.oe2003sp4.noarch", "openEuler-20.03-LTS-SP4:c3p0-help-0.9.5.4-4.oe2003sp4.noarch", "openEuler-22.03-LTS-SP4:c3p0-0.9.5.4-4.oe2203sp4.noarch", "openEuler-22.03-LTS-SP4:c3p0-help-0.9.5.4-4.oe2203sp4.noarch", "openEuler-24.03-LTS:c3p0-0.9.5.4-4.oe2403.noarch", "openEuler-24.03-LTS:c3p0-help-0.9.5.4-4.oe2403.noarch", "openEuler-24.03-LTS-SP1:c3p0-0.9.5.4-4.oe2403sp1.src", "openEuler-24.03-LTS-SP2:c3p0-0.9.5.4-4.oe2403sp2.src", "openEuler-24.03-LTS-SP3:c3p0-0.9.5.4-4.oe2403sp3.src", "openEuler-20.03-LTS-SP4:c3p0-0.9.5.4-4.oe2003sp4.src", "openEuler-22.03-LTS-SP4:c3p0-0.9.5.4-4.oe2203sp4.src", "openEuler-24.03-LTS:c3p0-0.9.5.4-4.oe2403.src" ] }, "remediations":[ { "product_ids":{ "$ref":"$.vulnerabilities[0].product_status.fixed" }, "details":"c3p0 security update", "category":"vendor_fix", "url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-1691" } ], "scores":[ { "cvss_v3":{ "baseSeverity":"HIGH", "baseScore":8.9, "vectorString":"CVSS:3.1/AV:A/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X", "version":"3.1" }, "products":{ "$ref":"$.vulnerabilities[0].product_status.fixed" } } ], "threats":[ { "details":"High", "category":"impact" } ], "title":"CVE-2026-27830" } ] }
