free5GC UDM CWE-388 Improper Error Handling Vulnerability Fix

Thinking Process: 1. Analyze the Request: Task: Translate a Chinese vulnerability intelligence summary to English. Role: Professional translator specializing in cybersecurity. Constraints: Maintain all Markdown formatting intact. Do not add any introductory or concluding remarks. Just output the English translation. Input: A Markdown snippet containing vulnerability details (Type, Description, Error Behavior, Reproduction Steps, Expected Behavior, Environment, Impact, Fix, References). 2. Analyze the Input Content: Title: (Critical Vulnerability Information) Section 1: (Vulnerability Type) -> (Already in English, keep as is). Section 2: (Vulnerability Description) -> Describes missing input validation on in UDM component's endpoint, leading to 500 errors instead of 4xx. Section 3: (Error Behavior) -> Lists Integer Overflow/Range Error and Invalid Syntax/Type Error with specific error messages. Section 4: (Reproduction Steps) -> Steps to reproduce using free5gc, curl commands, etc. Section 5: (Expected Behavior) -> UDM should validate data type and range, return 4xx for invalid params. Section 6: (Environment) -> free5GC version, OS, Kernel, Go version. Section 7: (Impact) -> CWE-388, info disclosure, fingerprinting. Section 8: (Fix) -> Fixed in PR #76, upgrade recommended. Section 9: (References) -> Issue report, PR link. 3. Drafting the Translation (Section by Section): -> -> -> (Keep as is) -> -> -> strconv.ParseInt: parsing... value out of range -> strconv.ParseInt: parsing... value out of range strconv.ParseInt: parsing... invalid syntax -> strconv.ParseInt: parsing... invalid syntax -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> -> 4. Review and Refine: Check Markdown syntax (headers, lists, code blocks, bold text). Ensure technical terms are accurate (e.g., "fuzzing", "fingerprinting", "endpoint", "parameter"). Ensure the tone is professional. Check specific strings like (keep as code). Check URLs (keep as is). One detail: "nrfcfg.yaml" is a filename, keep as is. "free5gc" vs "free5GC" - input uses mixed, standard is usually free5GC, but I should stick close to input or standardise. Input says "free5gc" in steps and "free5GC" in environment. I will use "free5GC" for consistency in English as it's the project name, but keep "free5gc" if it appears in code/command context. Actually, the input says "free5gc" in step 1 and "free5GC" in environment. I will standardize to "free5GC" for the project name in text, but keep command context natural. Input: -> Keep the as it indicates omitted path in the original text. Input: -> Keep as is. Input: -> Keep as is. Input: -> This looks like a future version (current is 1.21/1.22), but I must translate faithfully. Input: -> Keep. Input: -> Keep. Refining "Error Behavior": "Integer Overflow/Range Error" is good. "Invalid Syntax/Type Error" is good. Refining "Reproduction Steps": "HTTP message fuzzing" is a good translation for "HTTP 消息的模糊测试". Refining "Impact": "Service fingerprinting" is standard terminology. 5. Final Polish: Check against constraints. No intro/outro. Markdown intact. Wait, one check on the link: . The text says "Fix Pull Request" but the link points to an issue ( ). Usually PRs are . However, I should translate the text label "Fix Pull Request" accurately, even if the link might technically point to an issue in the source text. I will translate the label as "Fix Pull Request" or "Fix PR". The source says "修复 Pull 请求". I will use "Fix Pull Request". Actually, looking closely at the source: . The text says Pull Request, the link is an issue. I will translate the text label faithfully. One more check: "nrfcfg.yaml". In free5GC, it's usually or similar, but I must translate the text provided. "oauth 设为 false" -> "set oauth to false". Let's assemble. 6. Final Output Generation (matching the thought process). Looks good. I will ensure code blocks (backticks) are preserved. Wait, the input has . I should keep the exactly as is. Input: . Keep as is. Ready to write. One small nuance: "路径参数和查询参数" -> "path parameter and query parameter". "全面的输入验证" -> "comprehensive input validation". "客户端错误" -> "client error". "模糊测试" -> "fuzzing". "指纹识别" -> "fingerprinting". Let's go. Wait, checking the link again. . The text says "Fix Pull Request". I will translate it as "Fix Pull Request". Okay, proceeding. One detail: . "Critical Vulnerability Information" is standard. . "Vulnerability Type". . "Vulnerability Description". . "Error Behavior". . "Reproduction Steps". . "Expected Behavior". . "Environment". . "Impact". . "Fix" or "Remediation". "Fix" is shorter and matches the context of "Fixed in PR". . "References". Double check: "Do not add any introductory or concluding remarks". Just the markdown. Okay, final check on specific terms: "pduSessionId" -> keep camelCase. "Nudm_UECM" -> keep as is. "strconv.ParseInt" -> keep as code. "free5GC" -> Capitalize consistently where appropriate (Project name). "Ubuntu 20.04 服务器" -> "Ubuntu 20.04 Server". Let's const
