Output:
【漏洞类型】SQL注入
【严重性】High
【漏洞摘要】SQL注入是一种代码注入技术，攻击者可以通过在输入字段中插入恶意的SQL代码，操控数据库查询。在原始代码中，所有查询方法都直接将用户输入拼接到SQL语句中，例如`"SELECT wartosc,tematyka,nazwa from oceny_uczniow join rodzaje_aktywnosci ra on id_aktywnosci=ra.id where id_ucznia='" + studentID + "' and id_przedmiotu=" + subjectID + ";"`。这种做法使得攻击者可以通过构造特定的输入来执行任意的SQL命令，导致数据泄露、数据篡改或数据库服务崩溃。
【关键代码模式】
- 使用`Statement`对象执行SQL查询
- 将用户输入直接拼接到SQL语句中
- 缺乏输入验证和清理
【修复方法说明】修复方法通过将用户输入绑定到`PreparedStatement`对象的参数中来解决问题。这样可以确保用户输入不会被解释为SQL的一部分，从而防止SQL注入攻击。最佳实践是始终使用`PreparedStatement`来执行SQL查询，特别是在处理用户输入时。

Output:
【漏洞类型】权限管理漏洞
【严重性】High
【漏洞摘要】此代码存在权限管理漏洞，具体表现为在初始化文档权限时，未正确处理已设置的权限对象。如果文档中已存在一个权限对象，但其字段值为空或损坏，代码将不会检测到这一情况，并且会错误地认为文档尚未受到保护，从而导致权限设置不正确。根本原因在于代码中缺乏对现有权限对象的验证和修复逻辑。
【关键代码模式】
- `document.getXObjects(LOCAL_CLASS_REFERENCE).isEmpty()`：用于检查文档中是否已存在权限对象。
- `initializeRights(document, XWIKI_ADMIN_GROUP_DOCUMENT_REFERENCE, List.of(VIEW, EDIT, DELETE))`：初始化权限的方法。
- `object.set(GROUPS_FIELD_NAME, xwikiAdminGroupDocumentReference, xWikiContext)`：设置权限对象的组字段。
- `object.set(LEVELS_FIELD_NAME, rights.stream().map(Right::getName).collect(Collectors.toList()), xWikiContext)`：设置权限对象的权限级别字段。
- `object.set(ALLOW_FIELD_NAME, 1, xWikiContext)`：设置允许字段的值。
- `StringUtils.isEmpty(object.getStringValue(LEVELS_FIELD_NAME))` 和 `StringUtils.isEmpty(object.getLargeStringValue(GROUPS_FIELD_NAME))`：用于检查现有权限对象的字段值是否为空。
【修复方法说明】修复方法通过添加 `fixBadlyInitializedRights` 函数来检查和修复已存在但字段值损坏的权限对象。这解决了在文档升级过程中可能存在的权限初始化问题，确保了权限设置的正确性。最佳实践是在处理权限对象之前，始终验证其字段值，并在必要时进行修复。


Output:
【漏洞类型】远程代码执行（RCE）与路径遍历
【严重性】High
【漏洞摘要】原始代码中的 `git-receive-hook` 脚本允许任何本地地址访问，这可能导致恶意用户通过该脚本执行任意命令。此外，`DefaultProjectManager` 类中的 `isGitHookValid` 方法未验证 Git 钩子文件的内容，可能导致路径遍历漏洞。具体问题在于 `git-receive-hook` 脚本中未对传入的 `ENV_GIT_ALTERNATE_OBJECT_DIRECTORIES`、`ENV_GIT_OBJECT_DIRECTORY` 和 `ENV_GIT_QUARANTINE_PATH` 环境变量进行验证，而这些变量可以直接通过 HTTP POST 请求传入，从而导致潜在的路径遍历和远程代码执行问题。
【关键代码模式】
- `git-receive-hook` 脚本中的未验证的环境变量使用。
- `DefaultProjectManager` 类中的 `isGitHookValid` 方法未对 Git 钩子文件内容进行验证。
- `GitFilter` 和 `GitSshCommand` 类中对环境变量的设置。
【修复方法说明】修复通过在 `git-receive-hook` 脚本中添加 `ONEDEV_HOOK_TOKEN` 验证，并在 `DefaultProjectManager` 类中的 `isGitHookValid` 方法中检查该 token，防止未经授权的访问。

Output:
【漏洞类型】XWiki语法解析漏洞
【严重性】High
【漏洞摘要】原始代码中的RSS通知模板使用了XWiki语法解析，并且未对输出内容进行适当的编码或过滤。具体表现为，在`mentions.mention.vm`和`default.vm`文件中，`$newdoc.version`和`$diffLink`直接插入到HTML中，可能导致XWiki语法注入攻击。特别是在`default.vm`文件的第67行，`$services.localization.render('notifications.rss.seeChanges', 'xwiki/2.1', [$diffLink])`这一行，如果`$diffLink`包含恶意的XWiki语法，攻击者可以利用此漏洞执行任意XWiki代码。
【关键代码模式】$newdoc.version, $diffLink, $services.localization.render
【修复方法说明】通过将RSS feed内容直接写入响应输出流，并避免使用XWiki语法解析宏，修复了XWiki语法注入漏洞。最佳实践是在输出内容到HTML时进行适当的编码，以防止语法注入。

Output:
【漏洞类型】路径遍历漏洞
【严重性】High
【漏洞摘要】此代码存在路径遍历漏洞。`ClassPathResource`类的构造函数中未验证用户输入的路径是否包含`file:`前缀，这可能导致攻击者通过提供特定路径来访问文件系统中的任意文件。具体表现为`ClassPathResource`构造函数中对路径的处理，未对路径进行严格的验证和清理。
【关键代码模式】`ClassPathResource`构造函数中对路径的处理，特别是路径的格式检查和路径前缀的验证。相关关键词包括`ClassLoader.getResource`、`ClassLoader.getResourceAsStream`、`Class.getResource`、`Class.getResourceAsStream`、`StringUtils.cleanPath`。
【修复方法说明】修复方法通过添加`doesNotContainFileColon`方法来验证路径是否包含`file:`前缀，确保路径仅限于类路径资源。此修复方法遵循了输入验证的最佳实践，以防止路径遍历攻击。

Output:
【漏洞类型】路径遍历漏洞
【严重性】High
【漏洞摘要】这是一个路径遍历漏洞。在原始代码中，`ClassPathResource`类的构造函数`ClassPathResource(String path, ClassLoader classLoader)`和`ClassPathResource(String path)`中，路径参数`path`未经过严格的验证，可能导致攻击者通过构造恶意路径来访问类路径中不应该暴露的文件。具体表现为`doesNotContainFileColon(String path)`方法仅检查路径中是否包含`"file:"`，而未检查路径是否包含其他潜在的危险字符序列，如`"../"`。
【关键代码模式】未验证的用户输入路径、路径遍历检查不充分。
【修复方法说明】修复方法通过引入`isValid(String path)`和`isInvalidPath(String path)`方法，增加了对路径中包含`"WEB-INF"`、`"META-INF"`、`":/"`以及`"../"`等字符序列的检查，以防止路径遍历攻击。同时，遵循了安全编码的最佳实践，即对所有用户输入的路径进行严格的验证。

Output:
【漏洞类型】API Token Initialization Vulnerability
【严重性】Medium
【漏洞摘要】原始代码在初始化API token时，使用了用户ID和一个预定义的密钥（secret.key）来生成初始token。如果用户仍然拥有这个旧的初始token（例如，通过迁移或备份恢复），而系统没有检查并拒绝这个旧token，攻击者可以通过暴力破解这个旧token来访问用户的API权限。根本原因在于未验证用户当前API token是否为初始值，并在检测到初始值时生成新的token。
【关键代码模式】涉及用户身份验证的API token生成和验证逻辑，特别是使用用户特定信息（如user ID）和预定义密钥生成初始token的地方，以及在验证token时的逻辑。
【修复方法说明】修复方法在getApiToken函数中增加了对初始token的检查，如果检测到当前token是通过旧的密钥生成的，则强制生成新的token。这通过对比当前token与通过用户ID和Jenkins实例的secret key生成的初始token来实现。最佳实践是在系统中定期更换API token，并确保旧token在系统中失效。

Output:
【漏洞类型】业务逻辑漏洞
【严重性】High
【漏洞摘要】此代码在处理APE文件时，如果文件中没有帧（totalframes为0），在后续的帧处理过程中可能会导致无效的内存读取和写入。具体表现为在`ape_read_header`函数中，未检查`ape->totalframes`是否为0，直接分配内存并进行帧处理，可能导致空指针解引用或数组越界访问。
【关键代码模式】
- `ape_read_header`函数中，`ape->totalframes`的使用。
- `av_malloc`函数用于分配内存。
- `ape->frames`的使用。
【修复方法说明】增加对`ape->totalframes`是否为0的检查，如果为0则记录错误并返回`AVERROR(EINVAL)`，避免后续的无效内存操作。
